Given numbers are 761,664,430,669

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

The LCM of 761,664,430,669 is 72680400840.

Find LCM of 761,664,430,669 with Prime Factorization

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

2 x 761 x 332 x 215 x 669 = 72680400840

Therefore, the lowest common multiple of 761,664,430,669 is 72680400840.

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.

761 x 664 x 430 x 669 = 145360801680

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.

761 : 1, 761

664 : 1, 2, 4, 8, 83, 166, 332, 664

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

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 761,664,430,669, is 1.

Now, the common factors can be found like this.

761:761

664:2x 2x 2x 83

430:2x 5x 43

669:3x 223

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

2 = 2

Therefore, the value for common factors is 2.

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 = 145360801680/(1x2)

LCM = 145360801680/2

LCM = 72680400840

Thus, we can understand that the LCM of 761,664,430,669 is 72680400840.
