Calculate the LCM of 807,961,655,486,390

Given numbers are 807,961,655,486,390

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

The LCM of 807,961,655,486,390 is 1069785209610.

Find LCM of 807,961,655,486,390 with Prime Factorization


2 807, 961, 655, 486, 390
3 807, 961, 655, 243, 195
5 269, 961, 655, 81, 65
269, 961, 131, 81, 13

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

2 x 3 x 5 x 269 x 961 x 131 x 81 x 13 = 1069785209610

Therefore, the lowest common multiple of 807,961,655,486,390 is 1069785209610.

LCM Formula to Find Lowest Common Multiple of 807,961,655,486,390

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.

807 x 961 x 655 x 486 x 390 = 96280668864900

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.

807 : 1, 3, 269, 807

961 : 1, 31, 961

655 : 1, 5, 131, 655

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 807,961,655,486,390, is 1.

Now, the common factors can be found like this.

807:3x 269

961:31x 31

655:5x 131

486:2x 3x 3x 3x 3x 3

390:2x 3x 5x 13

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

2x 3x 3x 5 = 90

Therefore, the value for common factors is 90.

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 = 96280668864900/(1x90)

LCM = 96280668864900/90

LCM = 1069785209610

Thus, we can understand that the LCM of 807,961,655,486,390 is 1069785209610.
