This cannot be answered because the common multiples of any two or more numbers are infinite.
The Least Common Multiple (LCM) for 42 56 is 168.
There is no highest common multiple of 56, 98 and 168. Their highest common factor, which you may have meant, is 14.
Highest common factor is 7.
It is: 14
The least common multiple of the numbers 2,842 and 56 is 11,368.The least common multiple of the numbers 28, 42 and 56 is 168.
168
LCM(42, 56, 140) = 840
2184
The GCF is 14.
To find the least common multiple (LCM) of 21, 42, and 56, first find the prime factorization of each number. 21 = 3 x 7 42 = 2 x 3 x 7 56 = 2 x 2 x 2 x 7 Then, identify the highest power of each prime factor that appears in any of the factorizations. LCM = 2^3 x 3 x 7 = 56 x 3 x 7 = 1176 Therefore, the least common multiple of 21, 42, and 56 is 1176.
The LCM is: 168
The LCM is: 840
