The LCM of 290,209,294,639 is 1897759710.

Find LCM of 290,209,294,639 with Prime Factorization


2 290, 209, 294, 639
3 145, 209, 147, 639
145, 209, 49, 213

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

2 x 3 x 145 x 209 x 49 x 213 = 1897759710

Therefore, the lowest common multiple of 290,209,294,639 is 1897759710.

LCM Formula to Find Lowest Common Multiple of 290,209,294,639

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.

290 x 209 x 294 x 639 = 11386558260

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.

290 : 1, 2, 5, 10, 29, 58, 145, 290

209 : 1, 11, 19, 209

294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,209,294,639, is 1.

Now, the common factors can be found like this.

290:2x 5x 29

209:11x 19

294:2x 3x 7x 7

639:3x 3x 71

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 11386558260/(1x6)

LCM = 11386558260/6

LCM = 1897759710

Thus, we can understand that the LCM of 290,209,294,639 is 1897759710.
