Given numbers are 763,138,263,620

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

The LCM of 763,138,263,620 is 8584619820.

Find LCM of 763,138,263,620 with Prime Factorization

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

2 x 763 x 69 x 263 x 310 = 8584619820

Therefore, the lowest common multiple of 763,138,263,620 is 8584619820.

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.

763 x 138 x 263 x 620 = 17169239640

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.

763 : 1, 7, 109, 763

138 : 1, 2, 3, 6, 23, 46, 69, 138

263 : 1, 263

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,138,263,620, is 1.

Now, the common factors can be found like this.

763:7x 109

138:2x 3x 23

263:263

620:2x 2x 5x 31

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 = 17169239640/(1x2)

LCM = 17169239640/2

LCM = 8584619820

Thus, we can understand that the LCM of 763,138,263,620 is 8584619820.
