Given numbers are 674,682,577,420

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

The LCM of 674,682,577,420 is 27848985780.

Find LCM of 674,682,577,420 with Prime Factorization

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

2 x 337 x 341 x 577 x 210 = 27848985780

Therefore, the lowest common multiple of 674,682,577,420 is 27848985780.

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.

674 x 682 x 577 x 420 = 111395943120

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.

674 : 1, 2, 337, 674

682 : 1, 2, 11, 22, 31, 62, 341, 682

577 : 1, 577

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 674,682,577,420, is 1.

Now, the common factors can be found like this.

674:2x 337

682:2x 11x 31

577:577

420:2x 2x 3x 5x 7

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 111395943120/(1x4)

LCM = 111395943120/4

LCM = 27848985780

Thus, we can understand that the LCM of 674,682,577,420 is 27848985780.
