Calculate the LCM of 771,210,400,964

Given numbers are 771,210,400,964

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

The LCM of 771,210,400,964 is 520270800.

Find LCM of 771,210,400,964 with Prime Factorization


2 771, 210, 400, 964
2 771, 105, 200, 482
3 771, 105, 100, 241
5 257, 35, 100, 241
257, 7, 20, 241

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

2 x 2 x 3 x 5 x 257 x 7 x 20 x 241 = 520270800

Therefore, the lowest common multiple of 771,210,400,964 is 520270800.

LCM Formula to Find Lowest Common Multiple of 771,210,400,964

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 210 x 400 x 964 = 62432496000

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

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

964 : 1, 2, 4, 241, 482, 964

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,210,400,964, is 1.

Now, the common factors can be found like this.

771:3x 257

210:2x 3x 5x 7

400:2x 2x 2x 2x 5x 5

964:2x 2x 241

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 2x 3x 5 = 120

Therefore, the value for common factors is 120.

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 = 62432496000/(1x120)

LCM = 62432496000/120

LCM = 520270800

Thus, we can understand that the LCM of 771,210,400,964 is 520270800.
