Given numbers are 455,790,421,554

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

The LCM of 455,790,421,554 is 8383596130.

Find LCM of 455,790,421,554 with Prime Factorization

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

2 x 5 x 91 x 79 x 421 x 277 = 8383596130

Therefore, the lowest common multiple of 455,790,421,554 is 8383596130.

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 790 x 421 x 554 = 83835961300

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

790 : 1, 2, 5, 10, 79, 158, 395, 790

421 : 1, 421

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,790,421,554, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

790:2x 5x 79

421:421

554:2x 277

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 83835961300/(1x10)

LCM = 83835961300/10

LCM = 8383596130

Thus, we can understand that the LCM of 455,790,421,554 is 8383596130.
