Calculate the LCM of 395,135,946,630

Given numbers are 395,135,946,630

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

The LCM of 395,135,946,630 is 70623630.

Find LCM of 395,135,946,630 with Prime Factorization


2 395, 135, 946, 630
3 395, 135, 473, 315
3 395, 45, 473, 105
5 395, 15, 473, 35
79, 3, 473, 7

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

2 x 3 x 3 x 5 x 79 x 3 x 473 x 7 = 70623630

Therefore, the lowest common multiple of 395,135,946,630 is 70623630.

LCM Formula to Find Lowest Common Multiple of 395,135,946,630

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.

395 x 135 x 946 x 630 = 31780633500

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.

395 : 1, 5, 79, 395

135 : 1, 3, 5, 9, 15, 27, 45, 135

946 : 1, 2, 11, 22, 43, 86, 473, 946

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 395,135,946,630, is 1.

Now, the common factors can be found like this.

395:5x 79

135:3x 3x 3x 5

946:2x 11x 43

630:2x 3x 3x 5x 7

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

2x 3x 3x 5x 5 = 450

Therefore, the value for common factors is 450.

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 = 31780633500/(1x450)

LCM = 31780633500/450

LCM = 70623630

Thus, we can understand that the LCM of 395,135,946,630 is 70623630.
