Find LCM of 368,870,897,156,620 with Prime Factorization
| 2 | 368, 870, 897, 156, 620 |
| 2 | 184, 435, 897, 78, 310 |
| 3 | 92, 435, 897, 39, 155 |
| 5 | 92, 145, 299, 13, 155 |
| 13 | 92, 29, 299, 13, 31 |
| 23 | 92, 29, 23, 1, 31 |
| 4, 29, 1, 1, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 23 x 4 x 29 x 1 x 1 x 31 = 64512240
Therefore, the lowest common multiple of 368,870,897,156,620 is 64512240.
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.
368 x 870 x 897 x 156 x 620 = 27776390054400
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.
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
897 : 1, 3, 13, 23, 39, 69, 299, 897
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 368,870,897,156,620, is 1.
Now, the common factors can be found like this.
368:2x 2x 2x 2x 23
870:2x 3x 5x 29
897:3x 13x 23
156:2x 2x 3x 13
620:2x 2x 5x 31
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 2x 2x 3x 3x 5x 13x 23 = 430560
Therefore, the value for common factors is 430560.
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 = 27776390054400/(1x430560)
LCM = 27776390054400/430560
LCM = 64512240
Thus, we can understand that the LCM of 368,870,897,156,620 is 64512240.
