Find LCM of 616,420,679,636,505 with Prime Factorization
| 2 | 616, 420, 679, 636, 505 |
| 2 | 308, 210, 679, 318, 505 |
| 3 | 154, 105, 679, 159, 505 |
| 5 | 154, 35, 679, 53, 505 |
| 7 | 154, 7, 679, 53, 101 |
| 22, 1, 97, 53, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 22 x 1 x 97 x 53 x 101 = 4797786840
Therefore, the lowest common multiple of 616,420,679,636,505 is 4797786840.
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.
616 x 420 x 679 x 636 x 505 = 56421973238400
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.
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
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
679 : 1, 7, 97, 679
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,420,679,636,505, is 1.
Now, the common factors can be found like this.
616:2x 2x 2x 7x 11
420:2x 2x 3x 5x 7
679:7x 97
636:2x 2x 3x 53
505:5x 101
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 3x 5x 7x 7 = 11760
Therefore, the value for common factors is 11760.
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 = 56421973238400/(1x11760)
LCM = 56421973238400/11760
LCM = 4797786840
Thus, we can understand that the LCM of 616,420,679,636,505 is 4797786840.
