Given numbers are 477,136,131,220

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

The LCM of 477,136,131,220 is 467402760.

Find LCM of 477,136,131,220 with Prime Factorization

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

2 x 2 x 477 x 34 x 131 x 55 = 467402760

Therefore, the lowest common multiple of 477,136,131,220 is 467402760.

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.

477 x 136 x 131 x 220 = 1869611040

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.

477 : 1, 3, 9, 53, 159, 477

136 : 1, 2, 4, 8, 17, 34, 68, 136

131 : 1, 131

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 477,136,131,220, is 1.

Now, the common factors can be found like this.

477:3x 3x 53

136:2x 2x 2x 17

131:131

220:2x 2x 5x 11

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 1869611040/(1x4)

LCM = 1869611040/4

LCM = 467402760

Thus, we can understand that the LCM of 477,136,131,220 is 467402760.
