Given numbers are 702,620,791

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

The LCM of 702,620,791 is 172137420.

Find LCM of 702,620,791 with Prime Factorization

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

2 x 351 x 310 x 791 = 172137420

Therefore, the lowest common multiple of 702,620,791 is 172137420.

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.

702 x 620 x 791 = 344274840

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.

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

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

791 : 1, 7, 113, 791

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,620,791, is 1.

Now, the common factors can be found like this.

702:2x 3x 3x 3x 13

620:2x 2x 5x 31

791:7x 113

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

2 = 2

Therefore, the value for common factors is 2.

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 = 344274840/(1x2)

LCM = 344274840/2

LCM = 172137420

Thus, we can understand that the LCM of 702,620,791 is 172137420.
