Calculate the LCM of 774,373,391,721,436

Given numbers are 774,373,391,721,436

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

The LCM of 774,373,391,721,436 is 17742642755796.

Find LCM of 774,373,391,721,436 with Prime Factorization


2 774, 373, 391, 721, 436
387, 373, 391, 721, 218

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

2 x 387 x 373 x 391 x 721 x 218 = 17742642755796

Therefore, the lowest common multiple of 774,373,391,721,436 is 17742642755796.

LCM Formula to Find Lowest Common Multiple of 774,373,391,721,436

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.

774 x 373 x 391 x 721 x 436 = 35485285511592

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.

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

373 : 1, 373

391 : 1, 17, 23, 391

721 : 1, 7, 103, 721

436 : 1, 2, 4, 109, 218, 436

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,373,391,721,436, is 1.

Now, the common factors can be found like this.

774:2x 3x 3x 43

373:373

391:17x 23

721:7x 103

436:2x 2x 109

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 = 35485285511592/(1x2)

LCM = 35485285511592/2

LCM = 17742642755796

Thus, we can understand that the LCM of 774,373,391,721,436 is 17742642755796.
