Given numbers are 455,712,553,427

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

The LCM of 455,712,553,427 is 1561163240.

Find LCM of 455,712,553,427 with Prime Factorization

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

7 x 65 x 712 x 79 x 61 = 1561163240

Therefore, the lowest common multiple of 455,712,553,427 is 1561163240.

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.

455 x 712 x 553 x 427 = 76496998760

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.

455 : 1, 5, 7, 13, 35, 65, 91, 455

712 : 1, 2, 4, 8, 89, 178, 356, 712

553 : 1, 7, 79, 553

427 : 1, 7, 61, 427

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,712,553,427, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

712:2x 2x 2x 89

553:7x 79

427:7x 61

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

7x 7 = 49

Therefore, the value for common factors is 49.

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 = 76496998760/(1x49)

LCM = 76496998760/49

LCM = 1561163240

Thus, we can understand that the LCM of 455,712,553,427 is 1561163240.
