Calculate the LCM of 220,440,493,491

Given numbers are 220,440,493,491

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

The LCM of 220,440,493,491 is 106507720.

Find LCM of 220,440,493,491 with Prime Factorization


2 220, 440, 493, 491
2 110, 220, 493, 491
5 55, 110, 493, 491
11 11, 22, 493, 491
1, 2, 493, 491

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

2 x 2 x 5 x 11 x 1 x 2 x 493 x 491 = 106507720

Therefore, the lowest common multiple of 220,440,493,491 is 106507720.

LCM Formula to Find Lowest Common Multiple of 220,440,493,491

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.

220 x 440 x 493 x 491 = 23431698400

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.

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

493 : 1, 17, 29, 493

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,440,493,491, is 1.

Now, the common factors can be found like this.

220:2x 2x 5x 11

440:2x 2x 2x 5x 11

493:17x 29

491:491

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 5x 11 = 220

Therefore, the value for common factors is 220.

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 = 23431698400/(1x220)

LCM = 23431698400/220

LCM = 106507720

Thus, we can understand that the LCM of 220,440,493,491 is 106507720.
