Calculate the LCM of 669,494,419,490

Given numbers are 669,494,419,490

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

The LCM of 669,494,419,490 is 33926040330.

Find LCM of 669,494,419,490 with Prime Factorization


2 669, 494, 419, 490
669, 247, 419, 245

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

2 x 669 x 247 x 419 x 245 = 33926040330

Therefore, the lowest common multiple of 669,494,419,490 is 33926040330.

LCM Formula to Find Lowest Common Multiple of 669,494,419,490

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.

669 x 494 x 419 x 490 = 67852080660

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.

669 : 1, 3, 223, 669

494 : 1, 2, 13, 19, 26, 38, 247, 494

419 : 1, 419

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,494,419,490, is 1.

Now, the common factors can be found like this.

669:3x 223

494:2x 13x 19

419:419

490:2x 5x 7x 7

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 = 67852080660/(1x2)

LCM = 67852080660/2

LCM = 33926040330

Thus, we can understand that the LCM of 669,494,419,490 is 33926040330.
