Find LCM of 970,644,875,644 with Prime Factorization


2 970, 644, 875, 644
2 485, 322, 875, 322
5 485, 161, 875, 161
7 97, 161, 175, 161
23 97, 23, 25, 23
97, 1, 25, 1

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

2 x 2 x 5 x 7 x 23 x 97 x 1 x 25 x 1 = 7808500

Therefore, the lowest common multiple of 970,644,875,644 is 7808500.

LCM Formula to Find Lowest Common Multiple of 970,644,875,644

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.

970 x 644 x 875 x 644 = 352007180000

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.

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

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

875 : 1, 5, 7, 25, 35, 125, 175, 875

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 970,644,875,644, is 1.

Now, the common factors can be found like this.

970:2x 5x 97

644:2x 2x 7x 23

875:5x 5x 5x 7

644:2x 2x 7x 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 2x 5x 7x 7x 23 = 45080

Therefore, the value for common factors is 45080.

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 = 352007180000/(1x45080)

LCM = 352007180000/45080

LCM = 7808500

Thus, we can understand that the LCM of 970,644,875,644 is 7808500.
