Calculate the LCM of 715,645,755,612

Given numbers are 715,645,755,612

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

The LCM of 715,645,755,612 is 2841206940.

Find LCM of 715,645,755,612 with Prime Factorization


3 715, 645, 755, 612
5 715, 215, 755, 204
143, 43, 151, 204

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

3 x 5 x 143 x 43 x 151 x 204 = 2841206940

Therefore, the lowest common multiple of 715,645,755,612 is 2841206940.

LCM Formula to Find Lowest Common Multiple of 715,645,755,612

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.

715 x 645 x 755 x 612 = 213090520500

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.

715 : 1, 5, 11, 13, 55, 65, 143, 715

645 : 1, 3, 5, 15, 43, 129, 215, 645

755 : 1, 5, 151, 755

612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,645,755,612, is 1.

Now, the common factors can be found like this.

715:5x 11x 13

645:3x 5x 43

755:5x 151

612:2x 2x 3x 3x 17

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

3x 5x 5 = 75

Therefore, the value for common factors is 75.

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 = 213090520500/(1x75)

LCM = 213090520500/75

LCM = 2841206940

Thus, we can understand that the LCM of 715,645,755,612 is 2841206940.
