Given numbers are 545,430,686,997

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

The LCM of 545,430,686,997 is 16028180770.

Find LCM of 545,430,686,997 with Prime Factorization

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

2 x 5 x 109 x 43 x 343 x 997 = 16028180770

Therefore, the lowest common multiple of 545,430,686,997 is 16028180770.

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.

545 x 430 x 686 x 997 = 160281807700

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.

545 : 1, 5, 109, 545

430 : 1, 2, 5, 10, 43, 86, 215, 430

686 : 1, 2, 7, 14, 49, 98, 343, 686

997 : 1, 997

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,430,686,997, is 1.

Now, the common factors can be found like this.

545:5x 109

430:2x 5x 43

686:2x 7x 7x 7

997:997

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 = 160281807700/(1x10)

LCM = 160281807700/10

LCM = 16028180770

Thus, we can understand that the LCM of 545,430,686,997 is 16028180770.
