Calculate the LCM of 748,214,330,198,689

Given numbers are 748,214,330,198,689

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

The LCM of 748,214,330,198,689 is 2481516180.

Find LCM of 748,214,330,198,689 with Prime Factorization


2 748, 214, 330, 198, 689
3 374, 107, 165, 99, 689
11 374, 107, 55, 33, 689
34, 107, 5, 3, 689

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

2 x 3 x 11 x 34 x 107 x 5 x 3 x 689 = 2481516180

Therefore, the lowest common multiple of 748,214,330,198,689 is 2481516180.

LCM Formula to Find Lowest Common Multiple of 748,214,330,198,689

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.

748 x 214 x 330 x 198 x 689 = 7206322986720

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.

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

214 : 1, 2, 107, 214

330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,214,330,198,689, is 1.

Now, the common factors can be found like this.

748:2x 2x 11x 17

214:2x 107

330:2x 3x 5x 11

198:2x 3x 3x 11

689:13x 53

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 2x 3x 11x 11 = 2904

Therefore, the value for common factors is 2904.

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 = 7206322986720/(1x2904)

LCM = 7206322986720/2904

LCM = 2481516180

Thus, we can understand that the LCM of 748,214,330,198,689 is 2481516180.
