Given numbers are 648,537,438,623

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

The LCM of 648,537,438,623 is 5275200168.

Find LCM of 648,537,438,623 with Prime Factorization

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

2 x 3 x 108 x 179 x 73 x 623 = 5275200168

Therefore, the lowest common multiple of 648,537,438,623 is 5275200168.

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.

648 x 537 x 438 x 623 = 94953603024

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.

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

537 : 1, 3, 179, 537

438 : 1, 2, 3, 6, 73, 146, 219, 438

623 : 1, 7, 89, 623

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,537,438,623, is 1.

Now, the common factors can be found like this.

648:2x 2x 2x 3x 3x 3x 3

537:3x 179

438:2x 3x 73

623:7x 89

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 3 = 18

Therefore, the value for common factors is 18.

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 = 94953603024/(1x18)

LCM = 94953603024/18

LCM = 5275200168

Thus, we can understand that the LCM of 648,537,438,623 is 5275200168.
