Calculate the LCM of 817,620,430,387,311

Given numbers are 817,620,430,387,311

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

The LCM of 817,620,430,387,311 is 1417805460.

Find LCM of 817,620,430,387,311 with Prime Factorization


2 817, 620, 430, 387, 311
5 817, 310, 215, 387, 311
43 817, 62, 43, 387, 311
19, 62, 1, 9, 311

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

2 x 5 x 43 x 19 x 62 x 1 x 9 x 311 = 1417805460

Therefore, the lowest common multiple of 817,620,430,387,311 is 1417805460.

LCM Formula to Find Lowest Common Multiple of 817,620,430,387,311

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.

817 x 620 x 430 x 387 x 311 = 26215222955400

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.

817 : 1, 19, 43, 817

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

430 : 1, 2, 5, 10, 43, 86, 215, 430

387 : 1, 3, 9, 43, 129, 387

311 : 1, 311

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,620,430,387,311, is 1.

Now, the common factors can be found like this.

817:19x 43

620:2x 2x 5x 31

430:2x 5x 43

387:3x 3x 43

311:311

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

2x 5x 43x 43 = 18490

Therefore, the value for common factors is 18490.

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 = 26215222955400/(1x18490)

LCM = 26215222955400/18490

LCM = 1417805460

Thus, we can understand that the LCM of 817,620,430,387,311 is 1417805460.
