Calculate the LCM of 371,394,570,646

Given numbers are 371,394,570,646

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

The LCM of 371,394,570,646 is 708213030.

Find LCM of 371,394,570,646 with Prime Factorization


2 371, 394, 570, 646
19 371, 197, 285, 323
371, 197, 15, 17

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

2 x 19 x 371 x 197 x 15 x 17 = 708213030

Therefore, the lowest common multiple of 371,394,570,646 is 708213030.

LCM Formula to Find Lowest Common Multiple of 371,394,570,646

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.

371 x 394 x 570 x 646 = 53824190280

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.

371 : 1, 7, 53, 371

394 : 1, 2, 197, 394

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 371,394,570,646, is 1.

Now, the common factors can be found like this.

371:7x 53

394:2x 197

570:2x 3x 5x 19

646:2x 17x 19

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 19 = 76

Therefore, the value for common factors is 76.

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 = 53824190280/(1x76)

LCM = 53824190280/76

LCM = 708213030

Thus, we can understand that the LCM of 371,394,570,646 is 708213030.
