Given numbers are 420,847,702,919

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

The LCM of 420,847,702,919 is 5464318860.

Find LCM of 420,847,702,919 with Prime Factorization

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

2 x 3 x 7 x 10 x 121 x 117 x 919 = 5464318860

Therefore, the lowest common multiple of 420,847,702,919 is 5464318860.

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.

420 x 847 x 702 x 919 = 229501392120

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.

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

847 : 1, 7, 11, 77, 121, 847

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,847,702,919, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

847:7x 11x 11

702:2x 3x 3x 3x 13

919:919

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

2x 3x 7 = 42

Therefore, the value for common factors is 42.

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 = 229501392120/(1x42)

LCM = 229501392120/42

LCM = 5464318860

Thus, we can understand that the LCM of 420,847,702,919 is 5464318860.
