Given numbers are 973,421,667,638

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

The LCM of 973,421,667,638 is 6010954642.

Find LCM of 973,421,667,638 with Prime Factorization

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

29 x 973 x 421 x 23 x 22 = 6010954642

Therefore, the lowest common multiple of 973,421,667,638 is 6010954642.

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.

973 x 421 x 667 x 638 = 174317684618

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.

973 : 1, 7, 139, 973

421 : 1, 421

667 : 1, 23, 29, 667

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 973,421,667,638, is 1.

Now, the common factors can be found like this.

973:7x 139

421:421

667:23x 29

638:2x 11x 29

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

29 = 29

Therefore, the value for common factors is 29.

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 = 174317684618/(1x29)

LCM = 174317684618/29

LCM = 6010954642

Thus, we can understand that the LCM of 973,421,667,638 is 6010954642.
