Given numbers are 771,517,147,530,428

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

The LCM of 771,517,147,530,428 is 2215290291060.

Find LCM of 771,517,147,530,428 with Prime Factorization

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

2 x 3 x 257 x 517 x 49 x 265 x 214 = 2215290291060

Therefore, the lowest common multiple of 771,517,147,530,428 is 2215290291060.

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.

771 x 517 x 147 x 530 x 428 = 13291741746360

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.

771 : 1, 3, 257, 771

517 : 1, 11, 47, 517

147 : 1, 3, 7, 21, 49, 147

530 : 1, 2, 5, 10, 53, 106, 265, 530

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,517,147,530,428, is 1.

Now, the common factors can be found like this.

771:3x 257

517:11x 47

147:3x 7x 7

530:2x 5x 53

428:2x 2x 107

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 13291741746360/(1x6)

LCM = 13291741746360/6

LCM = 2215290291060

Thus, we can understand that the LCM of 771,517,147,530,428 is 2215290291060.
