Given numbers are 702,826,421,660

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

The LCM of 702,826,421,660 is 13426473060.

Find LCM of 702,826,421,660 with Prime Factorization

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

2 x 3 x 117 x 413 x 421 x 110 = 13426473060

Therefore, the lowest common multiple of 702,826,421,660 is 13426473060.

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 826 x 421 x 660 = 161117676720

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

826 : 1, 2, 7, 14, 59, 118, 413, 826

421 : 1, 421

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,826,421,660, is 1.

Now, the common factors can be found like this.

702:2x 3x 3x 3x 13

826:2x 7x 59

421:421

660:2x 2x 3x 5x 11

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 3 = 12

Therefore, the value for common factors is 12.

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 = 161117676720/(1x12)

LCM = 161117676720/12

LCM = 13426473060

Thus, we can understand that the LCM of 702,826,421,660 is 13426473060.
