Calculate the LCM of 419,791,790,238

Given numbers are 419,791,790,238

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

The LCM of 419,791,790,238 is 4451091470.

Find LCM of 419,791,790,238 with Prime Factorization


2 419, 791, 790, 238
7 419, 791, 395, 119
419, 113, 395, 17

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

2 x 7 x 419 x 113 x 395 x 17 = 4451091470

Therefore, the lowest common multiple of 419,791,790,238 is 4451091470.

LCM Formula to Find Lowest Common Multiple of 419,791,790,238

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.

419 x 791 x 790 x 238 = 62315280580

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.

419 : 1, 419

791 : 1, 7, 113, 791

790 : 1, 2, 5, 10, 79, 158, 395, 790

238 : 1, 2, 7, 14, 17, 34, 119, 238

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 419,791,790,238, is 1.

Now, the common factors can be found like this.

419:419

791:7x 113

790:2x 5x 79

238:2x 7x 17

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 62315280580/(1x14)

LCM = 62315280580/14

LCM = 4451091470

Thus, we can understand that the LCM of 419,791,790,238 is 4451091470.
