Given numbers are 247,562,456,690

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

The LCM of 247,562,456,690 is 191563320.

Find LCM of 247,562,456,690 with Prime Factorization

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

2 x 3 x 19 x 13 x 281 x 4 x 115 = 191563320

Therefore, the lowest common multiple of 247,562,456,690 is 191563320.

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.

247 x 562 x 456 x 690 = 43676436960

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.

247 : 1, 13, 19, 247

562 : 1, 2, 281, 562

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,562,456,690, is 1.

Now, the common factors can be found like this.

247:13x 19

562:2x 281

456:2x 2x 2x 3x 19

690:2x 3x 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 3x 19 = 228

Therefore, the value for common factors is 228.

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 = 43676436960/(1x228)

LCM = 43676436960/228

LCM = 191563320

Thus, we can understand that the LCM of 247,562,456,690 is 191563320.
