Find LCM of 290,420,507,301,774 with Prime Factorization


2 290, 420, 507, 301, 774
3 145, 210, 507, 301, 387
5 145, 70, 169, 301, 129
7 29, 14, 169, 301, 129
43 29, 2, 169, 43, 129
29, 2, 169, 1, 3

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

2 x 3 x 5 x 7 x 43 x 29 x 2 x 169 x 1 x 3 = 265536180

LCM Formula to Find Lowest Common Multiple of 290,420,507,301,774

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 420 x 507 x 301 x 774 = 14386750232400

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

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

507 : 1, 3, 13, 39, 169, 507

301 : 1, 7, 43, 301

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,420,507,301,774, is 1.

Now, the common factors can be found like this.

290:2x 5x 29

420:2x 2x 3x 5x 7

507:3x 13x 13

301:7x 43

774:2x 3x 3x 43

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 3x 5x 7x 43 = 54180

Therefore, the value for common factors is 54180.

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 = 14386750232400/(1x54180)

LCM = 14386750232400/54180

LCM = 265536180

Thus, we can understand that the LCM of 290,420,507,301,774 is 265536180.
