Given numbers are 620,720,771,995

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

The LCM of 620,720,771,995 is 1141511760.

Find LCM of 620,720,771,995 with Prime Factorization

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

2 x 2 x 3 x 5 x 31 x 12 x 257 x 199 = 1141511760

Therefore, the lowest common multiple of 620,720,771,995 is 1141511760.

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 720 x 771 x 995 = 342453528000

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

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

771 : 1, 3, 257, 771

995 : 1, 5, 199, 995

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,720,771,995, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

720:2x 2x 2x 2x 3x 3x 5

771:3x 257

995:5x 199

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 3x 5x 5 = 300

Therefore, the value for common factors is 300.

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 = 342453528000/(1x300)

LCM = 342453528000/300

LCM = 1141511760

Thus, we can understand that the LCM of 620,720,771,995 is 1141511760.
