Given numbers are 672,704,430,668

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

The LCM of 672,704,430,668 is 530819520.

Find LCM of 672,704,430,668 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 21 x 22 x 215 x 167 = 530819520

Therefore, the lowest common multiple of 672,704,430,668 is 530819520.

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.

672 x 704 x 430 x 668 = 135889797120

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.

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704

430 : 1, 2, 5, 10, 43, 86, 215, 430

668 : 1, 2, 4, 167, 334, 668

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,704,430,668, is 2.

Now, the common factors can be found like this.

672:2x 2x 2x 2x 2x 3x 7

704:2x 2x 2x 2x 2x 2x 11

430:2x 5x 43

668:2x 2x 167

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

2x 2x 2x 2x 2x 2x 2 = 128

Therefore, the value for common factors is 128.

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 = 135889797120/(2x128)

LCM = 135889797120/256

LCM = 530819520

Thus, we can understand that the LCM of 672,704,430,668 is 530819520.
