Given numbers are 660,136,421,626

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

The LCM of 660,136,421,626 is 2956986120.

Find LCM of 660,136,421,626 with Prime Factorization

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

2 x 2 x 165 x 34 x 421 x 313 = 2956986120

Therefore, the lowest common multiple of 660,136,421,626 is 2956986120.

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.

660 x 136 x 421 x 626 = 23655888960

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.

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

136 : 1, 2, 4, 8, 17, 34, 68, 136

421 : 1, 421

626 : 1, 2, 313, 626

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,136,421,626, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

136:2x 2x 2x 17

421:421

626:2x 313

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 2 = 8

Therefore, the value for common factors is 8.

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 = 23655888960/(1x8)

LCM = 23655888960/8

LCM = 2956986120

Thus, we can understand that the LCM of 660,136,421,626 is 2956986120.
