Given numbers are 763,986,407,781

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

The LCM of 763,986,407,781 is 21739733246.

Find LCM of 763,986,407,781 with Prime Factorization

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

11 x 763 x 986 x 37 x 71 = 21739733246

Therefore, the lowest common multiple of 763,986,407,781 is 21739733246.

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.

763 x 986 x 407 x 781 = 239137065706

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.

763 : 1, 7, 109, 763

986 : 1, 2, 17, 29, 34, 58, 493, 986

407 : 1, 11, 37, 407

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,986,407,781, is 1.

Now, the common factors can be found like this.

763:7x 109

986:2x 17x 29

407:11x 37

781:11x 71

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

11 = 11

Therefore, the value for common factors is 11.

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 = 239137065706/(1x11)

LCM = 239137065706/11

LCM = 21739733246

Thus, we can understand that the LCM of 763,986,407,781 is 21739733246.
