Given numbers are 840,492,906,254

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

The LCM of 840,492,906,254 is 660455880.

Find LCM of 840,492,906,254 with Prime Factorization

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

2 x 2 x 3 x 70 x 41 x 151 x 127 = 660455880

Therefore, the lowest common multiple of 840,492,906,254 is 660455880.

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 492 x 906 x 254 = 95105646720

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

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

906 : 1, 2, 3, 6, 151, 302, 453, 906

254 : 1, 2, 127, 254

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,492,906,254, is 2.

Now, the common factors can be found like this.

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

492:2x 2x 3x 41

906:2x 3x 151

254:2x 127

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 3x 3 = 72

Therefore, the value for common factors is 72.

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 = 95105646720/(2x72)

LCM = 95105646720/144

LCM = 660455880

Thus, we can understand that the LCM of 840,492,906,254 is 660455880.
