Calculate the LCM of 791,578,702,580

Given numbers are 791,578,702,580

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

The LCM of 791,578,702,580 is 46538184420.

Find LCM of 791,578,702,580 with Prime Factorization


2 791, 578, 702, 580
791, 289, 351, 290

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

2 x 791 x 289 x 351 x 290 = 46538184420

Therefore, the lowest common multiple of 791,578,702,580 is 46538184420.

LCM Formula to Find Lowest Common Multiple of 791,578,702,580

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.

791 x 578 x 702 x 580 = 186152737680

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.

791 : 1, 7, 113, 791

578 : 1, 2, 17, 34, 289, 578

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,578,702,580, is 1.

Now, the common factors can be found like this.

791:7x 113

578:2x 17x 17

702:2x 3x 3x 3x 13

580:2x 2x 5x 29

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 186152737680/(1x4)

LCM = 186152737680/4

LCM = 46538184420

Thus, we can understand that the LCM of 791,578,702,580 is 46538184420.
