Calculate the LCM of 709,391,904,638

Given numbers are 709,391,904,638

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

The LCM of 709,391,904,638 is 79943306344.

Find LCM of 709,391,904,638 with Prime Factorization


2 709, 391, 904, 638
709, 391, 452, 319

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

2 x 709 x 391 x 452 x 319 = 79943306344

Therefore, the lowest common multiple of 709,391,904,638 is 79943306344.

LCM Formula to Find Lowest Common Multiple of 709,391,904,638

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.

709 x 391 x 904 x 638 = 159886612688

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.

709 : 1, 709

391 : 1, 17, 23, 391

904 : 1, 2, 4, 8, 113, 226, 452, 904

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,391,904,638, is 1.

Now, the common factors can be found like this.

709:709

391:17x 23

904:2x 2x 2x 113

638:2x 11x 29

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 = 159886612688/(1x2)

LCM = 159886612688/2

LCM = 79943306344

Thus, we can understand that the LCM of 709,391,904,638 is 79943306344.
