The LCM of 684,912,457,251 is 313838352.

Find LCM of 684,912,457,251 with Prime Factorization


2 684, 912, 457, 251
2 342, 456, 457, 251
3 171, 228, 457, 251
19 57, 76, 457, 251
3, 4, 457, 251

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

2 x 2 x 3 x 19 x 3 x 4 x 457 x 251 = 313838352

Therefore, the lowest common multiple of 684,912,457,251 is 313838352.

LCM Formula to Find Lowest Common Multiple of 684,912,457,251

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.

684 x 912 x 457 x 251 = 71555144256

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.

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

457 : 1, 457

251 : 1, 251

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,912,457,251, is 1.

Now, the common factors can be found like this.

684:2x 2x 3x 3x 19

912:2x 2x 2x 2x 3x 19

457:457

251:251

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 3x 19 = 228

Therefore, the value for common factors is 228.

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 = 71555144256/(1x228)

LCM = 71555144256/228

LCM = 313838352

Thus, we can understand that the LCM of 684,912,457,251 is 313838352.
