Given numbers are 672,903,638,971

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

The LCM of 672,903,638,971 is 8950507104.

Find LCM of 672,903,638,971 with Prime Factorization

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

2 x 3 x 7 x 16 x 43 x 319 x 971 = 8950507104

Therefore, the lowest common multiple of 672,903,638,971 is 8950507104.

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 903 x 638 x 971 = 375921298368

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

903 : 1, 3, 7, 21, 43, 129, 301, 903

638 : 1, 2, 11, 22, 29, 58, 319, 638

971 : 1, 971

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,903,638,971, is 1.

Now, the common factors can be found like this.

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

903:3x 7x 43

638:2x 11x 29

971:971

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

2x 3x 7 = 42

Therefore, the value for common factors is 42.

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 = 375921298368/(1x42)

LCM = 375921298368/42

LCM = 8950507104

Thus, we can understand that the LCM of 672,903,638,971 is 8950507104.
