Given numbers are 642,107,763,997

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

The LCM of 642,107,763,997 is 488376462.

Find LCM of 642,107,763,997 with Prime Factorization

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

107 x 6 x 1 x 763 x 997 = 488376462

Therefore, the lowest common multiple of 642,107,763,997 is 488376462.

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.

642 x 107 x 763 x 997 = 52256281434

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

107 : 1, 107

763 : 1, 7, 109, 763

997 : 1, 997

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,107,763,997, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

107:107

763:7x 109

997:997

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

107 = 107

Therefore, the value for common factors is 107.

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 = 52256281434/(1x107)

LCM = 52256281434/107

LCM = 488376462

Thus, we can understand that the LCM of 642,107,763,997 is 488376462.
