Calculate the LCM of 842,784,655,491

Given numbers are 842,784,655,491

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

The LCM of 842,784,655,491 is 106150232720.

Find LCM of 842,784,655,491 with Prime Factorization


2 842, 784, 655, 491
421, 392, 655, 491

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

2 x 421 x 392 x 655 x 491 = 106150232720

Therefore, the lowest common multiple of 842,784,655,491 is 106150232720.

LCM Formula to Find Lowest Common Multiple of 842,784,655,491

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.

842 x 784 x 655 x 491 = 212300465440

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.

842 : 1, 2, 421, 842

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

655 : 1, 5, 131, 655

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,784,655,491, is 1.

Now, the common factors can be found like this.

842:2x 421

784:2x 2x 2x 2x 7x 7

655:5x 131

491:491

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 = 212300465440/(1x2)

LCM = 212300465440/2

LCM = 106150232720

Thus, we can understand that the LCM of 842,784,655,491 is 106150232720.
