Calculate the LCM of 394,417,210,770

Given numbers are 394,417,210,770

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

The LCM of 394,417,210,770 is 63254730.

Find LCM of 394,417,210,770 with Prime Factorization


2 394, 417, 210, 770
3 197, 417, 105, 385
5 197, 139, 35, 385
7 197, 139, 7, 77
197, 139, 1, 11

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

2 x 3 x 5 x 7 x 197 x 139 x 1 x 11 = 63254730

Therefore, the lowest common multiple of 394,417,210,770 is 63254730.

LCM Formula to Find Lowest Common Multiple of 394,417,210,770

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.

394 x 417 x 210 x 770 = 26566986600

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.

394 : 1, 2, 197, 394

417 : 1, 3, 139, 417

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,417,210,770, is 1.

Now, the common factors can be found like this.

394:2x 197

417:3x 139

210:2x 3x 5x 7

770:2x 5x 7x 11

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 5x 7 = 420

Therefore, the value for common factors is 420.

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 = 26566986600/(1x420)

LCM = 26566986600/420

LCM = 63254730

Thus, we can understand that the LCM of 394,417,210,770 is 63254730.
