Calculate the LCM of 639,620,842,529

Given numbers are 639,620,842,529

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

The LCM of 639,620,842,529 is 88232851620.

Find LCM of 639,620,842,529 with Prime Factorization


2 639, 620, 842, 529
639, 310, 421, 529

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

2 x 639 x 310 x 421 x 529 = 88232851620

Therefore, the lowest common multiple of 639,620,842,529 is 88232851620.

LCM Formula to Find Lowest Common Multiple of 639,620,842,529

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.

639 x 620 x 842 x 529 = 176465703240

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.

639 : 1, 3, 9, 71, 213, 639

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

842 : 1, 2, 421, 842

529 : 1, 23, 529

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,620,842,529, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

620:2x 2x 5x 31

842:2x 421

529:23x 23

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 = 176465703240/(1x2)

LCM = 176465703240/2

LCM = 88232851620

Thus, we can understand that the LCM of 639,620,842,529 is 88232851620.
