Calculate the LCM of 464,640,786,856

Given numbers are 464,640,786,856

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

The LCM of 464,640,786,856 is 780466560.

Find LCM of 464,640,786,856 with Prime Factorization


2 464, 640, 786, 856
2 232, 320, 393, 428
2 116, 160, 393, 214
2 58, 80, 393, 107
29, 40, 393, 107

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

2 x 2 x 2 x 2 x 29 x 40 x 393 x 107 = 780466560

Therefore, the lowest common multiple of 464,640,786,856 is 780466560.

LCM Formula to Find Lowest Common Multiple of 464,640,786,856

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.

464 x 640 x 786 x 856 = 199799439360

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.

464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

786 : 1, 2, 3, 6, 131, 262, 393, 786

856 : 1, 2, 4, 8, 107, 214, 428, 856

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 464,640,786,856, is 2.

Now, the common factors can be found like this.

464:2x 2x 2x 2x 29

640:2x 2x 2x 2x 2x 2x 2x 5

786:2x 3x 131

856:2x 2x 2x 107

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 2x 2x 2x 2 = 128

Therefore, the value for common factors is 128.

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 = 199799439360/(2x128)

LCM = 199799439360/256

LCM = 780466560

Thus, we can understand that the LCM of 464,640,786,856 is 780466560.
