The LCM of 781,862,504,857 is 145391716008.

Find LCM of 781,862,504,857 with Prime Factorization


2 781, 862, 504, 857
781, 431, 252, 857

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

2 x 781 x 431 x 252 x 857 = 145391716008

Therefore, the lowest common multiple of 781,862,504,857 is 145391716008.

LCM Formula to Find Lowest Common Multiple of 781,862,504,857

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 862 x 504 x 857 = 290783432016

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

862 : 1, 2, 431, 862

504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,862,504,857, is 1.

Now, the common factors can be found like this.

781:11x 71

862:2x 431

504:2x 2x 2x 3x 3x 7

857:857

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

2 = 2

Therefore, the value for common factors is 2.

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 = 290783432016/(1x2)

LCM = 290783432016/2

LCM = 145391716008

Thus, we can understand that the LCM of 781,862,504,857 is 145391716008.
