Calculate the LCM of 715,649,890,778

Given numbers are 715,649,890,778

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

The LCM of 715,649,890,778 is 2920973770.

Find LCM of 715,649,890,778 with Prime Factorization


2 715, 649, 890, 778
5 715, 649, 445, 389
11 143, 649, 89, 389
13, 59, 89, 389

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

2 x 5 x 11 x 13 x 59 x 89 x 389 = 2920973770

Therefore, the lowest common multiple of 715,649,890,778 is 2920973770.

LCM Formula to Find Lowest Common Multiple of 715,649,890,778

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.

715 x 649 x 890 x 778 = 321307114700

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.

715 : 1, 5, 11, 13, 55, 65, 143, 715

649 : 1, 11, 59, 649

890 : 1, 2, 5, 10, 89, 178, 445, 890

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,649,890,778, is 1.

Now, the common factors can be found like this.

715:5x 11x 13

649:11x 59

890:2x 5x 89

778:2x 389

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 11 = 110

Therefore, the value for common factors is 110.

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 = 321307114700/(1x110)

LCM = 321307114700/110

LCM = 2920973770

Thus, we can understand that the LCM of 715,649,890,778 is 2920973770.
