Calculate the LCM of 429,792,709,642

Given numbers are 429,792,709,642

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

The LCM of 429,792,709,642 is 781085448.

Find LCM of 429,792,709,642 with Prime Factorization


2 429, 792, 709, 642
3 429, 396, 709, 321
11 143, 132, 709, 107
13, 12, 709, 107

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

2 x 3 x 11 x 13 x 12 x 709 x 107 = 781085448

Therefore, the lowest common multiple of 429,792,709,642 is 781085448.

LCM Formula to Find Lowest Common Multiple of 429,792,709,642

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.

429 x 792 x 709 x 642 = 154654918704

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.

429 : 1, 3, 11, 13, 33, 39, 143, 429

792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792

709 : 1, 709

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,792,709,642, is 1.

Now, the common factors can be found like this.

429:3x 11x 13

792:2x 2x 2x 3x 3x 11

709:709

642:2x 3x 107

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 3x 11 = 198

Therefore, the value for common factors is 198.

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 = 154654918704/(1x198)

LCM = 154654918704/198

LCM = 781085448

Thus, we can understand that the LCM of 429,792,709,642 is 781085448.
