Find LCM of 636,462,759,421 with Prime Factorization


2 636, 462, 759, 421
3 318, 231, 759, 421
11 106, 77, 253, 421
106, 7, 23, 421

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

2 x 3 x 11 x 106 x 7 x 23 x 421 = 474195876

Therefore, the lowest common multiple of 636,462,759,421 is 474195876.

LCM Formula to Find Lowest Common Multiple of 636,462,759,421

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.

636 x 462 x 759 x 421 = 93890783448

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.

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462

759 : 1, 3, 11, 23, 33, 69, 253, 759

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,462,759,421, is 1.

Now, the common factors can be found like this.

636:2x 2x 3x 53

462:2x 3x 7x 11

759:3x 11x 23

421:421

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 = 93890783448/(1x198)

LCM = 93890783448/198

LCM = 474195876

Thus, we can understand that the LCM of 636,462,759,421 is 474195876.
