Calculate the LCM of 980,150,815,639

Given numbers are 980,150,815,639

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

The LCM of 980,150,815,639 is 510369300.

Find LCM of 980,150,815,639 with Prime Factorization


2 980, 150, 815, 639
3 490, 75, 815, 639
5 490, 25, 815, 213
98, 5, 163, 213

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

2 x 3 x 5 x 98 x 5 x 163 x 213 = 510369300

Therefore, the lowest common multiple of 980,150,815,639 is 510369300.

LCM Formula to Find Lowest Common Multiple of 980,150,815,639

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.

980 x 150 x 815 x 639 = 76555395000

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.

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150

815 : 1, 5, 163, 815

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,150,815,639, is 1.

Now, the common factors can be found like this.

980:2x 2x 5x 7x 7

150:2x 3x 5x 5

815:5x 163

639:3x 3x 71

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

2x 3x 5x 5 = 150

Therefore, the value for common factors is 150.

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 = 76555395000/(1x150)

LCM = 76555395000/150

LCM = 510369300

Thus, we can understand that the LCM of 980,150,815,639 is 510369300.
