Given numbers are 620,393,131,347

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

The LCM of 620,393,131,347 is 84550020.

Find LCM of 620,393,131,347 with Prime Factorization

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

131 x 620 x 3 x 1 x 347 = 84550020

Therefore, the lowest common multiple of 620,393,131,347 is 84550020.

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.

620 x 393 x 131 x 347 = 11076052620

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

393 : 1, 3, 131, 393

131 : 1, 131

347 : 1, 347

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,393,131,347, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

393:3x 131

131:131

347:347

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

131 = 131

Therefore, the value for common factors is 131.

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 = 11076052620/(1x131)

LCM = 11076052620/131

LCM = 84550020

Thus, we can understand that the LCM of 620,393,131,347 is 84550020.
