Calculating the Least Common Multiple (LCM)

To calculate the least common multiple (LCM) for the given numbers, we need to find the smallest number that is divisible by all the given numbers. Here are the calculations for each set of numbers:

a) 13 and 5: To find the LCM of 13 and 5, we can start by listing the multiples of each number and finding the first common multiple: - Multiples of 13: 13, 26, 39, 52, 65, ... - Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, ... The first common multiple is 65, so the LCM of 13 and 5 is 65.

c) 35 and 49: To find the LCM of 35 and 49, we can follow the same process: - Multiples of 35: 35, 70, 105, 140, 175, ... - Multiples of 49: 49, 98, 147, 196, 245, ... The first common multiple is 245, so the LCM of 35 and 49 is 245.

e) 4200 and 16,500: To find the LCM of 4200 and 16,500, we can follow the same process: - Multiples of 4200: 4200, 8400, 12,600, 16,800, ... - Multiples of 16,500: 16,500, 33,000, 49,500, 66,000, ... The first common multiple is 231,000, so the LCM of 4200 and 16,500 is 231,000.

b) 70 and 35: To find the LCM of 70 and 35, we can follow the same process: - Multiples of 70: 70, 140, 210, 280, ... - Multiples of 35: 35, 70, 105, 140, ... The first common multiple is 70, so the LCM of 70 and 35 is 70.

d) 24 and 60: To find the LCM of 24 and 60, we can follow the same process: - Multiples of 24: 24, 48, 72, 96, ... - Multiples of 60: 60, 120, 180, 240, ... The first common multiple is 120, so the LCM of 24 and 60 is 120.

f) 126, 182, and 42: To find the LCM of 126, 182, and 42, we can follow the same process: - Multiples of 126: 126, 252, 378, 504, ... - Multiples of 182: 182, 364, 546, 728, ... - Multiples of 42: 42, 84, 126, 168, ... The first common multiple is 1,914, so the LCM of 126, 182, and 42 is 1,914.

Therefore, the LCM for the given numbers is: A) 65 B) 70 C) 245 D) 120 E) 231,000 F) 1,914
