Calculate the LCM of 985,415,102,728,689

Given numbers are 985,415,102,728,689

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

The LCM of 985,415,102,728,689 is 160876180920.

Find LCM of 985,415,102,728,689 with Prime Factorization


2 985, 415, 102, 728, 689
5 985, 415, 51, 364, 689
13 197, 83, 51, 364, 689
197, 83, 51, 28, 53

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

2 x 5 x 13 x 197 x 83 x 51 x 28 x 53 = 160876180920

Therefore, the lowest common multiple of 985,415,102,728,689 is 160876180920.

LCM Formula to Find Lowest Common Multiple of 985,415,102,728,689

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.

985 x 415 x 102 x 728 x 689 = 20913903519600

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.

985 : 1, 5, 197, 985

415 : 1, 5, 83, 415

102 : 1, 2, 3, 6, 17, 34, 51, 102

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,415,102,728,689, is 1.

Now, the common factors can be found like this.

985:5x 197

415:5x 83

102:2x 3x 17

728:2x 2x 2x 7x 13

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 5x 13 = 130

Therefore, the value for common factors is 130.

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 = 20913903519600/(1x130)

LCM = 20913903519600/130

LCM = 160876180920

Thus, we can understand that the LCM of 985,415,102,728,689 is 160876180920.
