This cannot be answered because the common multiples of any two or more numbers are infinite.
There is no highest common multiple of 56, 98 and 168. Their highest common factor, which you may have meant, is 14.
The Least Common Multiple (LCM) for 28 21 56 is 168.
The least common multiple of 3, 21, and 56 is 168.
The least common multiple (LCM) of 21, 56, and 63 is 504.
The greatest, (Highest) Common Factor of 21 and 56 is 7
The greatest common multiple of any set of integers is infinite.
The GCF of 35 and 56 is 7.The LCM of 35 and 56 is 280.
840
The highest common factor is 7
The GCF is 7.
The least common multiple (LCM) of 18, 21, and 56 is 504.
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.
