Given numbers are 840,812,392,718

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

The LCM of 840,812,392,718 is 61216680.

Find LCM of 840,812,392,718 with Prime Factorization

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

2 x 2 x 2 x 7 x 15 x 29 x 7 x 359 = 61216680

Therefore, the lowest common multiple of 840,812,392,718 is 61216680.

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.

840 x 812 x 392 x 718 = 191975508480

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.

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

718 : 1, 2, 359, 718

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,812,392,718, is 2.

Now, the common factors can be found like this.

840:2x 2x 2x 3x 5x 7

812:2x 2x 7x 29

392:2x 2x 2x 7x 7

718:2x 359

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 2x 2x 2x 7x 7 = 1568

Therefore, the value for common factors is 1568.

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 = 191975508480/(2x1568)

LCM = 191975508480/3136

LCM = 61216680

Thus, we can understand that the LCM of 840,812,392,718 is 61216680.
