Calculate the LCM of 392,118,216,394

Given numbers are 392,118,216,394

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

The LCM of 392,118,216,394 is 123017832.

Find LCM of 392,118,216,394 with Prime Factorization


2 392, 118, 216, 394
2 196, 59, 108, 197
2 98, 59, 54, 197
49, 59, 27, 197

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

2 x 2 x 2 x 49 x 59 x 27 x 197 = 123017832

Therefore, the lowest common multiple of 392,118,216,394 is 123017832.

LCM Formula to Find Lowest Common Multiple of 392,118,216,394

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.

392 x 118 x 216 x 394 = 3936570624

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.

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

118 : 1, 2, 59, 118

216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216

394 : 1, 2, 197, 394

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,118,216,394, is 2.

Now, the common factors can be found like this.

392:2x 2x 2x 7x 7

118:2x 59

216:2x 2x 2x 3x 3x 3

394:2x 197

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 3936570624/(2x16)

LCM = 3936570624/32

LCM = 123017832

Thus, we can understand that the LCM of 392,118,216,394 is 123017832.
