Calculate the LCM of 889,989,670,860

Given numbers are 889,989,670,860

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

The LCM of 889,989,670,860 is 1178156140.

Find LCM of 889,989,670,860 with Prime Factorization


2 889, 989, 670, 860
5 889, 989, 335, 430
43 889, 989, 67, 86
889, 23, 67, 2

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

2 x 5 x 43 x 889 x 23 x 67 x 2 = 1178156140

Therefore, the lowest common multiple of 889,989,670,860 is 1178156140.

LCM Formula to Find Lowest Common Multiple of 889,989,670,860

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.

889 x 989 x 670 x 860 = 506607140200

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.

889 : 1, 7, 127, 889

989 : 1, 23, 43, 989

670 : 1, 2, 5, 10, 67, 134, 335, 670

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 889,989,670,860, is 1.

Now, the common factors can be found like this.

889:7x 127

989:23x 43

670:2x 5x 67

860:2x 2x 5x 43

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

2x 5x 43 = 430

Therefore, the value for common factors is 430.

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 = 506607140200/(1x430)

LCM = 506607140200/430

LCM = 1178156140

Thus, we can understand that the LCM of 889,989,670,860 is 1178156140.
