The LCM of 143,374,247,470 is 21708830.

Find LCM of 143,374,247,470 with Prime Factorization


2 143, 374, 247, 470
11 143, 187, 247, 235
13 13, 17, 247, 235
1, 17, 19, 235

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

2 x 11 x 13 x 1 x 17 x 19 x 235 = 21708830

Therefore, the lowest common multiple of 143,374,247,470 is 21708830.

LCM Formula to Find Lowest Common Multiple of 143,374,247,470

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.

143 x 374 x 247 x 470 = 6208725380

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.

143 : 1, 11, 13, 143

374 : 1, 2, 11, 17, 22, 34, 187, 374

247 : 1, 13, 19, 247

470 : 1, 2, 5, 10, 47, 94, 235, 470

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,374,247,470, is 1.

Now, the common factors can be found like this.

143:11x 13

374:2x 11x 17

247:13x 19

470:2x 5x 47

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 11x 13 = 286

Therefore, the value for common factors is 286.

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 = 6208725380/(1x286)

LCM = 6208725380/286

LCM = 21708830

Thus, we can understand that the LCM of 143,374,247,470 is 21708830.
