Calculate the LCM of 382,742,671,770

Given numbers are 382,742,671,770

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

The LCM of 382,742,671,770 is 475477310.

Find LCM of 382,742,671,770 with Prime Factorization


2 382, 742, 671, 770
7 191, 371, 671, 385
11 191, 53, 671, 55
191, 53, 61, 5

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

2 x 7 x 11 x 191 x 53 x 61 x 5 = 475477310

Therefore, the lowest common multiple of 382,742,671,770 is 475477310.

LCM Formula to Find Lowest Common Multiple of 382,742,671,770

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.

382 x 742 x 671 x 770 = 146447011480

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.

382 : 1, 2, 191, 382

742 : 1, 2, 7, 14, 53, 106, 371, 742

671 : 1, 11, 61, 671

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,742,671,770, is 1.

Now, the common factors can be found like this.

382:2x 191

742:2x 7x 53

671:11x 61

770:2x 5x 7x 11

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

2x 2x 7x 11 = 308

Therefore, the value for common factors is 308.

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 = 146447011480/(1x308)

LCM = 146447011480/308

LCM = 475477310

Thus, we can understand that the LCM of 382,742,671,770 is 475477310.
