Calculate the LCM of 7,620,446,385

Given numbers are 7,620,446,385

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

The LCM of 7,620,446,385 is 10646020.

Find LCM of 7,620,446,385 with Prime Factorization


2 7, 620, 446, 385
5 7, 310, 223, 385
7 7, 62, 223, 77
1, 62, 223, 11

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

2 x 5 x 7 x 1 x 62 x 223 x 11 = 10646020

Therefore, the lowest common multiple of 7,620,446,385 is 10646020.

LCM Formula to Find Lowest Common Multiple of 7,620,446,385

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.

7 x 620 x 446 x 385 = 745221400

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.

7 : 1, 7

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

446 : 1, 2, 223, 446

385 : 1, 5, 7, 11, 35, 55, 77, 385

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,620,446,385, is 1.

Now, the common factors can be found like this.

7:7

620:2x 2x 5x 31

446:2x 223

385:5x 7x 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 5x 7 = 70

Therefore, the value for common factors is 70.

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 = 745221400/(1x70)

LCM = 745221400/70

LCM = 10646020

Thus, we can understand that the LCM of 7,620,446,385 is 10646020.
