Calculate the LCM of 172,970,786,956

Given numbers are 172,970,786,956

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

The LCM of 172,970,786,956 is 7835390340.

Find LCM of 172,970,786,956 with Prime Factorization


2 172, 970, 786, 956
2 86, 485, 393, 478
43, 485, 393, 239

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

2 x 2 x 43 x 485 x 393 x 239 = 7835390340

Therefore, the lowest common multiple of 172,970,786,956 is 7835390340.

LCM Formula to Find Lowest Common Multiple of 172,970,786,956

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.

172 x 970 x 786 x 956 = 125366245440

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.

172 : 1, 2, 4, 43, 86, 172

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

786 : 1, 2, 3, 6, 131, 262, 393, 786

956 : 1, 2, 4, 239, 478, 956

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,970,786,956, is 2.

Now, the common factors can be found like this.

172:2x 2x 43

970:2x 5x 97

786:2x 3x 131

956:2x 2x 239

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 2 = 8

Therefore, the value for common factors is 8.

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 = 125366245440/(2x8)

LCM = 125366245440/16

LCM = 7835390340

Thus, we can understand that the LCM of 172,970,786,956 is 7835390340.
