Find LCM of 890,799,878,785,178 with Prime Factorization


2 890, 799, 878, 785, 178
5 445, 799, 439, 785, 89
89 89, 799, 439, 157, 89
1, 799, 439, 157, 1

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

2 x 5 x 89 x 1 x 799 x 439 x 157 x 1 = 49011834530

Therefore, the lowest common multiple of 890,799,878,785,178 is 49011834530.

LCM Formula to Find Lowest Common Multiple of 890,799,878,785,178

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.

890 x 799 x 878 x 785 x 178 = 87241065463400

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.

890 : 1, 2, 5, 10, 89, 178, 445, 890

799 : 1, 17, 47, 799

878 : 1, 2, 439, 878

785 : 1, 5, 157, 785

178 : 1, 2, 89, 178

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,799,878,785,178, is 1.

Now, the common factors can be found like this.

890:2x 5x 89

799:17x 47

878:2x 439

785:5x 157

178:2x 89

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 5x 89 = 1780

Therefore, the value for common factors is 1780.

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 = 87241065463400/(1x1780)

LCM = 87241065463400/1780

LCM = 49011834530

Thus, we can understand that the LCM of 890,799,878,785,178 is 49011834530.
