Given numbers are 656,717,661,478

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 656,717,661,478 is 310902672.

Find LCM of 656,717,661,478 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 239 x 328 x 3 x 661 x 1 = 310902672

Therefore, the lowest common multiple of 656,717,661,478 is 310902672.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

656 x 717 x 661 x 478 = 148611477216

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

717 : 1, 3, 239, 717

661 : 1, 661

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 656,717,661,478, is 1.

Now, the common factors can be found like this.

656:2x 2x 2x 2x 41

717:3x 239

661:661

478:2x 239

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 239 = 478

Therefore, the value for common factors is 478.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 148611477216/(1x478)

LCM = 148611477216/478

LCM = 310902672

Thus, we can understand that the LCM of 656,717,661,478 is 310902672.
