What is the LCM of 98 and 49?
The Least Common Multiple (LCM) of 98 and 49 is 49.
Is 98 a multiple of 14?
To determine if 98 is a multiple of 14, we need to divide 98 by 14. When we do this division, we find that 98 ÷ 14 = 7. Since the division results in a whole number (7), we can conclude that 98 is indeed a multiple of 14.

It is: 2/7 of 98 = 28
How do you know if a number is a multiple of 7?
There is a trick to figuring out whether a number is divisible by 7, without having to divide it directly. Unfortunately, the 'shortcut' is almost as hard as simply doing the division in the first place.But for those who want to know, here's the trick:Take the final digit of the number.Double it.Subtract it from the rest of the digits.Repeat until you get a number that is (or isn't) a multiple of 7.For example, try 98:The final digit is 8.8 x 2 = 16.9 (98, without the 8) - 16 = -7.-7 is a multiple of 7, so 98 is divisible by 7.
What is the LCM of 98 56 28?
To find the Least Common Multiple (LCM) of 98, 56, and 28, we first need to find the prime factorization of each number. The prime factorization of 98 is 2 * 7^2, the prime factorization of 56 is 2^3 * 7, and the prime factorization of 28 is 2^2 * 7. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers. Therefore, the LCM of 98, 56, and 28 is 2^3 * 7^2, which equals 392.
