Calculate the LCM of 626,436,975,643

Given numbers are 626,436,975,643

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

The LCM of 626,436,975,643 is 85555200900.

Find LCM of 626,436,975,643 with Prime Factorization


2 626, 436, 975, 643
313, 218, 975, 643

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

2 x 313 x 218 x 975 x 643 = 85555200900

Therefore, the lowest common multiple of 626,436,975,643 is 85555200900.

LCM Formula to Find Lowest Common Multiple of 626,436,975,643

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.

626 x 436 x 975 x 643 = 171110401800

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.

626 : 1, 2, 313, 626

436 : 1, 2, 4, 109, 218, 436

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,436,975,643, is 1.

Now, the common factors can be found like this.

626:2x 313

436:2x 2x 109

975:3x 5x 5x 13

643:643

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 = 171110401800/(1x2)

LCM = 171110401800/2

LCM = 85555200900

Thus, we can understand that the LCM of 626,436,975,643 is 85555200900.
