Calculate the LCM of 771,257,985,850

Given numbers are 771,257,985,850

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

The LCM of 771,257,985,850 is 129103950.

Find LCM of 771,257,985,850 with Prime Factorization


5 771, 257, 985, 850
257 771, 257, 197, 170
3, 1, 197, 170

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

5 x 257 x 3 x 1 x 197 x 170 = 129103950

Therefore, the lowest common multiple of 771,257,985,850 is 129103950.

LCM Formula to Find Lowest Common Multiple of 771,257,985,850

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.

771 x 257 x 985 x 850 = 165898575750

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.

771 : 1, 3, 257, 771

257 : 1, 257

985 : 1, 5, 197, 985

850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,257,985,850, is 1.

Now, the common factors can be found like this.

771:3x 257

257:257

985:5x 197

850:2x 5x 5x 17

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

5x 257 = 1285

Therefore, the value for common factors is 1285.

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 = 165898575750/(1x1285)

LCM = 165898575750/1285

LCM = 129103950

Thus, we can understand that the LCM of 771,257,985,850 is 129103950.
