Calculate the LCM of 692,668,145,494

Given numbers are 692,668,145,494

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

The LCM of 692,668,145,494 is 4138924660.

Find LCM of 692,668,145,494 with Prime Factorization


2 692, 668, 145, 494
2 346, 334, 145, 247
173, 167, 145, 247

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

2 x 2 x 173 x 167 x 145 x 247 = 4138924660

Therefore, the lowest common multiple of 692,668,145,494 is 4138924660.

LCM Formula to Find Lowest Common Multiple of 692,668,145,494

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.

692 x 668 x 145 x 494 = 33111397280

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.

692 : 1, 2, 4, 173, 346, 692

668 : 1, 2, 4, 167, 334, 668

145 : 1, 5, 29, 145

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 692,668,145,494, is 1.

Now, the common factors can be found like this.

692:2x 2x 173

668:2x 2x 167

145:5x 29

494:2x 13x 19

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 2 = 8

Therefore, the value for common factors is 8.

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 = 33111397280/(1x8)

LCM = 33111397280/8

LCM = 4138924660

Thus, we can understand that the LCM of 692,668,145,494 is 4138924660.
