Given numbers are 781,724,248,551

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

The LCM of 781,724,248,551 is 19316697928.

Find LCM of 781,724,248,551 with Prime Factorization

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

2 x 2 x 781 x 181 x 62 x 551 = 19316697928

Therefore, the lowest common multiple of 781,724,248,551 is 19316697928.

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 724 x 248 x 551 = 77266791712

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

724 : 1, 2, 4, 181, 362, 724

248 : 1, 2, 4, 8, 31, 62, 124, 248

551 : 1, 19, 29, 551

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,724,248,551, is 1.

Now, the common factors can be found like this.

781:11x 71

724:2x 2x 181

248:2x 2x 2x 31

551:19x 29

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 77266791712/(1x4)

LCM = 77266791712/4

LCM = 19316697928

Thus, we can understand that the LCM of 781,724,248,551 is 19316697928.
