Given numbers are 781,994,872,554

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

The LCM of 781,994,872,554 is 1320521048.

Find LCM of 781,994,872,554 with Prime Factorization

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

2 x 71 x 11 x 7 x 436 x 277 = 1320521048

Therefore, the lowest common multiple of 781,994,872,554 is 1320521048.

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.

781 x 994 x 872 x 554 = 375027977632

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.

781 : 1, 11, 71, 781

994 : 1, 2, 7, 14, 71, 142, 497, 994

872 : 1, 2, 4, 8, 109, 218, 436, 872

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,994,872,554, is 1.

Now, the common factors can be found like this.

781:11x 71

994:2x 7x 71

872:2x 2x 2x 109

554:2x 277

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 71 = 284

Therefore, the value for common factors is 284.

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 = 375027977632/(1x284)

LCM = 375027977632/284

LCM = 1320521048

Thus, we can understand that the LCM of 781,994,872,554 is 1320521048.
