Given numbers are 781,836,437,153

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

The LCM of 781,836,437,153 is 208873764.

Find LCM of 781,836,437,153 with Prime Factorization

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

11 x 19 x 71 x 4 x 23 x 153 = 208873764

Therefore, the lowest common multiple of 781,836,437,153 is 208873764.

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 836 x 437 x 153 = 43654616676

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

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

437 : 1, 19, 23, 437

153 : 1, 3, 9, 17, 51, 153

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,836,437,153, is 1.

Now, the common factors can be found like this.

781:11x 71

836:2x 2x 11x 19

437:19x 23

153:3x 3x 17

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

11x 19 = 209

Therefore, the value for common factors is 209.

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 = 43654616676/(1x209)

LCM = 43654616676/209

LCM = 208873764

Thus, we can understand that the LCM of 781,836,437,153 is 208873764.
