Given numbers are 781,532,793,551,138

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

The LCM of 781,532,793,551,138 is 659299797156.

Find LCM of 781,532,793,551,138 with Prime Factorization

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

2 x 19 x 781 x 14 x 793 x 29 x 69 = 659299797156

Therefore, the lowest common multiple of 781,532,793,551,138 is 659299797156.

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 532 x 793 x 551 x 138 = 25053392291928

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

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

793 : 1, 13, 61, 793

551 : 1, 19, 29, 551

138 : 1, 2, 3, 6, 23, 46, 69, 138

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,532,793,551,138, is 1.

Now, the common factors can be found like this.

781:11x 71

532:2x 2x 7x 19

793:13x 61

551:19x 29

138:2x 3x 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 19 = 38

Therefore, the value for common factors is 38.

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 = 25053392291928/(1x38)

LCM = 25053392291928/38

LCM = 659299797156

Thus, we can understand that the LCM of 781,532,793,551,138 is 659299797156.
