Calculate the LCM of 709,894,860,688

Given numbers are 709,894,860,688

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

The LCM of 709,894,860,688 is 1090215120.

Find LCM of 709,894,860,688 with Prime Factorization


2 709, 894, 860, 688
2 709, 447, 430, 344
43 709, 447, 215, 172
709, 447, 5, 4

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

2 x 2 x 43 x 709 x 447 x 5 x 4 = 1090215120

Therefore, the lowest common multiple of 709,894,860,688 is 1090215120.

LCM Formula to Find Lowest Common Multiple of 709,894,860,688

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 894 x 860 x 688 = 375034001280

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

894 : 1, 2, 3, 6, 149, 298, 447, 894

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,894,860,688, is 1.

Now, the common factors can be found like this.

709:709

894:2x 3x 149

860:2x 2x 5x 43

688:2x 2x 2x 2x 43

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

2x 2x 2x 43 = 344

Therefore, the value for common factors is 344.

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 = 375034001280/(1x344)

LCM = 375034001280/344

LCM = 1090215120

Thus, we can understand that the LCM of 709,894,860,688 is 1090215120.
