Calculate the LCM of 620,702,726,710

Given numbers are 620,702,726,710

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

The LCM of 620,702,726,710 is 1869573420.

Find LCM of 620,702,726,710 with Prime Factorization


2 620, 702, 726, 710
3 310, 351, 363, 355
5 310, 117, 121, 355
62, 117, 121, 71

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

2 x 3 x 5 x 62 x 117 x 121 x 71 = 1869573420

Therefore, the lowest common multiple of 620,702,726,710 is 1869573420.

LCM Formula to Find Lowest Common Multiple of 620,702,726,710

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.

620 x 702 x 726 x 710 = 224348810400

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

710 : 1, 2, 5, 10, 71, 142, 355, 710

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,702,726,710, is 2.

Now, the common factors can be found like this.

620:2x 2x 5x 31

702:2x 3x 3x 3x 13

726:2x 3x 11x 11

710:2x 5x 71

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 3x 5 = 60

Therefore, the value for common factors is 60.

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 = 224348810400/(2x60)

LCM = 224348810400/120

LCM = 1869573420

Thus, we can understand that the LCM of 620,702,726,710 is 1869573420.
