The LCM of 671,615,319,492 is 47869140.

Find LCM of 671,615,319,492 with Prime Factorization


3 671, 615, 319, 492
11 671, 205, 319, 164
41 61, 205, 29, 164
61, 5, 29, 4

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

3 x 11 x 41 x 61 x 5 x 29 x 4 = 47869140

Therefore, the lowest common multiple of 671,615,319,492 is 47869140.

LCM Formula to Find Lowest Common Multiple of 671,615,319,492

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.

671 x 615 x 319 x 492 = 64766946420

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.

671 : 1, 11, 61, 671

615 : 1, 3, 5, 15, 41, 123, 205, 615

319 : 1, 11, 29, 319

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,615,319,492, is 1.

Now, the common factors can be found like this.

671:11x 61

615:3x 5x 41

319:11x 29

492:2x 2x 3x 41

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

3x 11x 41 = 1353

Therefore, the value for common factors is 1353.

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 = 64766946420/(1x1353)

LCM = 64766946420/1353

LCM = 47869140

Thus, we can understand that the LCM of 671,615,319,492 is 47869140.
