Calculate the LCM of 656,723,970,801,690

Given numbers are 656,723,970,801,690

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

The LCM of 656,723,970,801,690 is 1412612264880.

Find LCM of 656,723,970,801,690 with Prime Factorization


2 656, 723, 970, 801, 690
3 328, 723, 485, 801, 345
5 328, 241, 485, 267, 115
328, 241, 97, 267, 23

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

2 x 3 x 5 x 328 x 241 x 97 x 267 x 23 = 1412612264880

Therefore, the lowest common multiple of 656,723,970,801,690 is 1412612264880.

LCM Formula to Find Lowest Common Multiple of 656,723,970,801,690

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.

656 x 723 x 970 x 801 x 690 = 254270207678400

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.

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

723 : 1, 3, 241, 723

970 : 1, 2, 5, 10, 97, 194, 485, 970

801 : 1, 3, 9, 89, 267, 801

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 656,723,970,801,690, is 1.

Now, the common factors can be found like this.

656:2x 2x 2x 2x 41

723:3x 241

970:2x 5x 97

801:3x 3x 89

690:2x 3x 5x 23

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 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 254270207678400/(1x180)

LCM = 254270207678400/180

LCM = 1412612264880

Thus, we can understand that the LCM of 656,723,970,801,690 is 1412612264880.
