Given numbers are 545,674,780,698

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

The LCM of 545,674,780,698 is 9999457260.

Find LCM of 545,674,780,698 with Prime Factorization

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

2 x 5 x 109 x 337 x 78 x 349 = 9999457260

Therefore, the lowest common multiple of 545,674,780,698 is 9999457260.

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 674 x 780 x 698 = 199989145200

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

674 : 1, 2, 337, 674

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

698 : 1, 2, 349, 698

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,674,780,698, is 1.

Now, the common factors can be found like this.

545:5x 109

674:2x 337

780:2x 2x 3x 5x 13

698:2x 349

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 199989145200/(1x20)

LCM = 199989145200/20

LCM = 9999457260

Thus, we can understand that the LCM of 545,674,780,698 is 9999457260.
