Calculate the LCM of 476,364,640,423

Given numbers are 476,364,640,423

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

The LCM of 476,364,640,423 is 418803840.

Find LCM of 476,364,640,423 with Prime Factorization


2 476, 364, 640, 423
2 238, 182, 320, 423
7 119, 91, 160, 423
17, 13, 160, 423

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

2 x 2 x 7 x 17 x 13 x 160 x 423 = 418803840

Therefore, the lowest common multiple of 476,364,640,423 is 418803840.

LCM Formula to Find Lowest Common Multiple of 476,364,640,423

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.

476 x 364 x 640 x 423 = 46906030080

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.

476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476

364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364

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

423 : 1, 3, 9, 47, 141, 423

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,364,640,423, is 1.

Now, the common factors can be found like this.

476:2x 2x 7x 17

364:2x 2x 7x 13

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

423:3x 3x 47

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 7 = 112

Therefore, the value for common factors is 112.

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 = 46906030080/(1x112)

LCM = 46906030080/112

LCM = 418803840

Thus, we can understand that the LCM of 476,364,640,423 is 418803840.
