Calculate the LCM of 379,842,140,407

Given numbers are 379,842,140,407

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

The LCM of 379,842,140,407 is 9091671820.

Find LCM of 379,842,140,407 with Prime Factorization


2 379, 842, 140, 407
379, 421, 70, 407

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

2 x 379 x 421 x 70 x 407 = 9091671820

Therefore, the lowest common multiple of 379,842,140,407 is 9091671820.

LCM Formula to Find Lowest Common Multiple of 379,842,140,407

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.

379 x 842 x 140 x 407 = 18183343640

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.

379 : 1, 379

842 : 1, 2, 421, 842

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 379,842,140,407, is 1.

Now, the common factors can be found like this.

379:379

842:2x 421

140:2x 2x 5x 7

407:11x 37

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

2 = 2

Therefore, the value for common factors is 2.

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 = 18183343640/(1x2)

LCM = 18183343640/2

LCM = 9091671820

Thus, we can understand that the LCM of 379,842,140,407 is 9091671820.
