Calculate the LCM of 272,974,689,689

Given numbers are 272,974,689,689

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

The LCM of 272,974,689,689 is 91267696.

Find LCM of 272,974,689,689 with Prime Factorization


2 272, 974, 689, 689
13 136, 487, 689, 689
53 136, 487, 53, 53
136, 487, 1, 1

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

2 x 13 x 53 x 136 x 487 x 1 x 1 = 91267696

Therefore, the lowest common multiple of 272,974,689,689 is 91267696.

LCM Formula to Find Lowest Common Multiple of 272,974,689,689

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.

272 x 974 x 689 x 689 = 125766885088

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.

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

974 : 1, 2, 487, 974

689 : 1, 13, 53, 689

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 272,974,689,689, is 1.

Now, the common factors can be found like this.

272:2x 2x 2x 2x 17

974:2x 487

689:13x 53

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 13x 53 = 1378

Therefore, the value for common factors is 1378.

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 = 125766885088/(1x1378)

LCM = 125766885088/1378

LCM = 91267696

Thus, we can understand that the LCM of 272,974,689,689 is 91267696.
