Find LCM of 420,917,195,607,572 with Prime Factorization
| 2 | 420, 917, 195, 607, 572 |
| 2 | 210, 917, 195, 607, 286 |
| 3 | 105, 917, 195, 607, 143 |
| 5 | 35, 917, 65, 607, 143 |
| 7 | 7, 917, 13, 607, 143 |
| 13 | 1, 131, 13, 607, 143 |
| 1, 131, 1, 607, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 13 x 1 x 131 x 1 x 607 x 11 = 4775791020
Therefore, the lowest common multiple of 420,917,195,607,572 is 4775791020.
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.
420 x 917 x 195 x 607 x 572 = 26075818969200
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.
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
917 : 1, 7, 131, 917
195 : 1, 3, 5, 13, 15, 39, 65, 195
607 : 1, 607
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,917,195,607,572, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
917:7x 131
195:3x 5x 13
607:607
572:2x 2x 11x 13
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 3x 5x 7x 13 = 5460
Therefore, the value for common factors is 5460.
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 = 26075818969200/(1x5460)
LCM = 26075818969200/5460
LCM = 4775791020
Thus, we can understand that the LCM of 420,917,195,607,572 is 4775791020.
