Calculate the LCM of 636,722,391,745

Given numbers are 636,722,391,745

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

The LCM of 636,722,391,745 is 66880166820.

Find LCM of 636,722,391,745 with Prime Factorization


2 636, 722, 391, 745
318, 361, 391, 745

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

2 x 318 x 361 x 391 x 745 = 66880166820

Therefore, the lowest common multiple of 636,722,391,745 is 66880166820.

LCM Formula to Find Lowest Common Multiple of 636,722,391,745

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 722 x 391 x 745 = 133760333640

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

722 : 1, 2, 19, 38, 361, 722

391 : 1, 17, 23, 391

745 : 1, 5, 149, 745

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,722,391,745, is 1.

Now, the common factors can be found like this.

636:2x 2x 3x 53

722:2x 19x 19

391:17x 23

745:5x 149

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 = 133760333640/(1x2)

LCM = 133760333640/2

LCM = 66880166820

Thus, we can understand that the LCM of 636,722,391,745 is 66880166820.
