Calculate the LCM of 975,189,639,299

Given numbers are 975,189,639,299

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

The LCM of 975,189,639,299 is 100307025.

Find LCM of 975,189,639,299 with Prime Factorization


3 975, 189, 639, 299
3 325, 63, 213, 299
13 325, 21, 71, 299
25, 21, 71, 23

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

3 x 3 x 13 x 25 x 21 x 71 x 23 = 100307025

Therefore, the lowest common multiple of 975,189,639,299 is 100307025.

LCM Formula to Find Lowest Common Multiple of 975,189,639,299

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.

975 x 189 x 639 x 299 = 35207765775

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.

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

189 : 1, 3, 7, 9, 21, 27, 63, 189

639 : 1, 3, 9, 71, 213, 639

299 : 1, 13, 23, 299

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 975,189,639,299, is 1.

Now, the common factors can be found like this.

975:3x 5x 5x 13

189:3x 3x 3x 7

639:3x 3x 71

299:13x 23

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

3x 3x 3x 13 = 351

Therefore, the value for common factors is 351.

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 = 35207765775/(1x351)

LCM = 35207765775/351

LCM = 100307025

Thus, we can understand that the LCM of 975,189,639,299 is 100307025.
