Calculate the LCM of 998,971,620,491

Given numbers are 998,971,620,491

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

The LCM of 998,971,620,491 is 147500318180.

Find LCM of 998,971,620,491 with Prime Factorization


2 998, 971, 620, 491
499, 971, 310, 491

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

2 x 499 x 971 x 310 x 491 = 147500318180

Therefore, the lowest common multiple of 998,971,620,491 is 147500318180.

LCM Formula to Find Lowest Common Multiple of 998,971,620,491

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.

998 x 971 x 620 x 491 = 295000636360

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.

998 : 1, 2, 499, 998

971 : 1, 971

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,971,620,491, is 1.

Now, the common factors can be found like this.

998:2x 499

971:971

620:2x 2x 5x 31

491:491

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 = 295000636360/(1x2)

LCM = 295000636360/2

LCM = 147500318180

Thus, we can understand that the LCM of 998,971,620,491 is 147500318180.
