Find LCM of 355,572,312,289,390 with Prime Factorization
2 | 355, 572, 312, 289, 390 |
2 | 355, 286, 156, 289, 195 |
3 | 355, 143, 78, 289, 195 |
5 | 355, 143, 26, 289, 65 |
13 | 71, 143, 26, 289, 13 |
71, 11, 2, 289, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 71 x 11 x 2 x 289 x 1 = 352106040
Therefore, the lowest common multiple of 355,572,312,289,390 is 352106040.
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.
355 x 572 x 312 x 289 x 390 = 7140710491200
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.
355 : 1, 5, 71, 355
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
289 : 1, 17, 289
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,572,312,289,390, is 1.
Now, the common factors can be found like this.
355:5x 71
572:2x 2x 11x 13
312:2x 2x 2x 3x 13
289:17x 17
390:2x 3x 5x 13
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 2x 3x 5x 13x 13 = 20280
Therefore, the value for common factors is 20280.
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 = 7140710491200/(1x20280)
LCM = 7140710491200/20280
LCM = 352106040
Thus, we can understand that the LCM of 355,572,312,289,390 is 352106040.
