Find LCM of 174,340,465,492,391 with Prime Factorization
| 2 | 174, 340, 465, 492, 391 |
| 2 | 87, 170, 465, 246, 391 |
| 3 | 87, 85, 465, 123, 391 |
| 5 | 29, 85, 155, 41, 391 |
| 17 | 29, 17, 31, 41, 391 |
| 29, 1, 31, 41, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 17 x 29 x 1 x 31 x 41 x 23 = 864712140
Therefore, the lowest common multiple of 174,340,465,492,391 is 864712140.
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.
174 x 340 x 465 x 492 x 391 = 5292038296800
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.
174 : 1, 2, 3, 6, 29, 58, 87, 174
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
465 : 1, 3, 5, 15, 31, 93, 155, 465
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 174,340,465,492,391, is 1.
Now, the common factors can be found like this.
174:2x 3x 29
340:2x 2x 5x 17
465:3x 5x 31
492:2x 2x 3x 41
391:17x 23
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 3x 5x 17 = 6120
Therefore, the value for common factors is 6120.
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 = 5292038296800/(1x6120)
LCM = 5292038296800/6120
LCM = 864712140
Thus, we can understand that the LCM of 174,340,465,492,391 is 864712140.
