Calculate the LCM of 620,917,766,305

Given numbers are 620,917,766,305

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

The LCM of 620,917,766,305 is 13282800020.

Find LCM of 620,917,766,305 with Prime Factorization


2 620, 917, 766, 305
5 310, 917, 383, 305
62, 917, 383, 61

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

2 x 5 x 62 x 917 x 383 x 61 = 13282800020

Therefore, the lowest common multiple of 620,917,766,305 is 13282800020.

LCM Formula to Find Lowest Common Multiple of 620,917,766,305

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 917 x 766 x 305 = 132828000200

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

917 : 1, 7, 131, 917

766 : 1, 2, 383, 766

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,917,766,305, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

917:7x 131

766:2x 383

305:5x 61

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 132828000200/(1x10)

LCM = 132828000200/10

LCM = 13282800020

Thus, we can understand that the LCM of 620,917,766,305 is 13282800020.
