Find LCM of 606,616,420,240 with Prime Factorization
| 2 | 606, 616, 420, 240 |
| 2 | 303, 308, 210, 120 |
| 2 | 303, 154, 105, 60 |
| 3 | 303, 77, 105, 30 |
| 5 | 101, 77, 35, 10 |
| 7 | 101, 77, 7, 2 |
| 101, 11, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 101 x 11 x 1 x 2 = 1866480
Therefore, the lowest common multiple of 606,616,420,240 is 1866480.
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.
606 x 616 x 420 x 240 = 37628236800
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.
606 : 1, 2, 3, 6, 101, 202, 303, 606
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
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 606,616,420,240, is 2.
Now, the common factors can be found like this.
606:2x 3x 101
616:2x 2x 2x 7x 11
420:2x 2x 3x 5x 7
240:2x 2x 2x 2x 3x 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 3x 3x 5x 7 = 10080
Therefore, the value for common factors is 10080.
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 = 37628236800/(2x10080)
LCM = 37628236800/20160
LCM = 1866480
Thus, we can understand that the LCM of 606,616,420,240 is 1866480.
