Calculate the LCM of 568,715,138,700

Given numbers are 568,715,138,700

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

The LCM of 568,715,138,700 is 980779800.

Find LCM of 568,715,138,700 with Prime Factorization


2 568, 715, 138, 700
2 284, 715, 69, 350
5 142, 715, 69, 175
142, 143, 69, 35

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

2 x 2 x 5 x 142 x 143 x 69 x 35 = 980779800

Therefore, the lowest common multiple of 568,715,138,700 is 980779800.

LCM Formula to Find Lowest Common Multiple of 568,715,138,700

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.

568 x 715 x 138 x 700 = 39231192000

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.

568 : 1, 2, 4, 8, 71, 142, 284, 568

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 568,715,138,700, is 1.

Now, the common factors can be found like this.

568:2x 2x 2x 71

715:5x 11x 13

138:2x 3x 23

700:2x 2x 5x 5x 7

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 2x 5 = 40

Therefore, the value for common factors is 40.

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 = 39231192000/(1x40)

LCM = 39231192000/40

LCM = 980779800

Thus, we can understand that the LCM of 568,715,138,700 is 980779800.
