Calculate the LCM of 721,767,904,668

Given numbers are 721,767,904,668

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

The LCM of 721,767,904,668 is 83486360776.

Find LCM of 721,767,904,668 with Prime Factorization


2 721, 767, 904, 668
2 721, 767, 452, 334
721, 767, 226, 167

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

2 x 2 x 721 x 767 x 226 x 167 = 83486360776

Therefore, the lowest common multiple of 721,767,904,668 is 83486360776.

LCM Formula to Find Lowest Common Multiple of 721,767,904,668

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.

721 x 767 x 904 x 668 = 333945443104

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.

721 : 1, 7, 103, 721

767 : 1, 13, 59, 767

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

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,767,904,668, is 1.

Now, the common factors can be found like this.

721:7x 103

767:13x 59

904:2x 2x 2x 113

668:2x 2x 167

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 333945443104/(1x4)

LCM = 333945443104/4

LCM = 83486360776

Thus, we can understand that the LCM of 721,767,904,668 is 83486360776.
