Given numbers are 434,680,630,421,115

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

The LCM of 434,680,630,421,115 is 12859411320.

Find LCM of 434,680,630,421,115 with Prime Factorization

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

2 x 5 x 7 x 31 x 68 x 9 x 421 x 23 = 12859411320

Therefore, the lowest common multiple of 434,680,630,421,115 is 12859411320.

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.

434 x 680 x 630 x 421 x 115 = 9001587924000

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.

434 : 1, 2, 7, 14, 31, 62, 217, 434

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

421 : 1, 421

115 : 1, 5, 23, 115

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 434,680,630,421,115, is 1.

Now, the common factors can be found like this.

434:2x 7x 31

680:2x 2x 2x 5x 17

630:2x 3x 3x 5x 7

421:421

115:5x 23

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 5x 5x 7 = 700

Therefore, the value for common factors is 700.

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 = 9001587924000/(1x700)

LCM = 9001587924000/700

LCM = 12859411320

Thus, we can understand that the LCM of 434,680,630,421,115 is 12859411320.
