Calculate the LCM of 640,434,577,351

Given numbers are 640,434,577,351

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

The LCM of 640,434,577,351 is 28126949760.

Find LCM of 640,434,577,351 with Prime Factorization


2 640, 434, 577, 351
320, 217, 577, 351

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

2 x 320 x 217 x 577 x 351 = 28126949760

Therefore, the lowest common multiple of 640,434,577,351 is 28126949760.

LCM Formula to Find Lowest Common Multiple of 640,434,577,351

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.

640 x 434 x 577 x 351 = 56253899520

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.

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

434 : 1, 2, 7, 14, 31, 62, 217, 434

577 : 1, 577

351 : 1, 3, 9, 13, 27, 39, 117, 351

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,434,577,351, is 1.

Now, the common factors can be found like this.

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

434:2x 7x 31

577:577

351:3x 3x 3x 13

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

2 = 2

Therefore, the value for common factors is 2.

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 = 56253899520/(1x2)

LCM = 56253899520/2

LCM = 28126949760

Thus, we can understand that the LCM of 640,434,577,351 is 28126949760.
