Find LCM of 611,720,374,616,640 with Prime Factorization
| 2 | 611, 720, 374, 616, 640 |
| 2 | 611, 360, 187, 308, 320 |
| 2 | 611, 180, 187, 154, 160 |
| 2 | 611, 90, 187, 77, 80 |
| 5 | 611, 45, 187, 77, 40 |
| 11 | 611, 9, 187, 77, 8 |
| 611, 9, 17, 7, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 11 x 611 x 9 x 17 x 7 x 8 = 4606842240
Therefore, the lowest common multiple of 611,720,374,616,640 is 4606842240.
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.
611 x 720 x 374 x 616 x 640 = 64864338739200
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.
611 : 1, 13, 47, 611
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
374 : 1, 2, 11, 17, 22, 34, 187, 374
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,720,374,616,640, is 1.
Now, the common factors can be found like this.
611:13x 47
720:2x 2x 2x 2x 3x 3x 5
374:2x 11x 17
616:2x 2x 2x 7x 11
640:2x 2x 2x 2x 2x 2x 2x 5
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 2x 2x 2x 5x 11 = 14080
Therefore, the value for common factors is 14080.
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 = 64864338739200/(1x14080)
LCM = 64864338739200/14080
LCM = 4606842240
Thus, we can understand that the LCM of 611,720,374,616,640 is 4606842240.
