Given numbers are 655,404,402,774

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

The LCM of 655,404,402,774 is 6861331980.

Find LCM of 655,404,402,774 with Prime Factorization

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

2 x 3 x 655 x 202 x 67 x 129 = 6861331980

Therefore, the lowest common multiple of 655,404,402,774 is 6861331980.

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.

655 x 404 x 402 x 774 = 82335983760

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.

655 : 1, 5, 131, 655

404 : 1, 2, 4, 101, 202, 404

402 : 1, 2, 3, 6, 67, 134, 201, 402

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,404,402,774, is 1.

Now, the common factors can be found like this.

655:5x 131

404:2x 2x 101

402:2x 3x 67

774:2x 3x 3x 43

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 3 = 12

Therefore, the value for common factors is 12.

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 = 82335983760/(1x12)

LCM = 82335983760/12

LCM = 6861331980

Thus, we can understand that the LCM of 655,404,402,774 is 6861331980.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 522, 829, 156, 112
