Given numbers are 868,430,752,649,638

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

The LCM of 868,430,752,649,638 is 660326503760.

Find LCM of 868,430,752,649,638 with Prime Factorization

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

2 x 2 x 11 x 217 x 215 x 188 x 59 x 29 = 660326503760

Therefore, the lowest common multiple of 868,430,752,649,638 is 660326503760.

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.

868 x 430 x 752 x 649 x 638 = 116217464661760

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.

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

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

752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752

649 : 1, 11, 59, 649

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 868,430,752,649,638, is 1.

Now, the common factors can be found like this.

868:2x 2x 7x 31

430:2x 5x 43

752:2x 2x 2x 2x 47

649:11x 59

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.

2x 2x 2x 2x 11 = 176

Therefore, the value for common factors is 176.

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 = 116217464661760/(1x176)

LCM = 116217464661760/176

LCM = 660326503760

Thus, we can understand that the LCM of 868,430,752,649,638 is 660326503760.
