Find LCM of 570,434,228,916,620 with Prime Factorization
| 2 | 570, 434, 228, 916, 620 |
| 2 | 285, 217, 114, 458, 310 |
| 3 | 285, 217, 57, 229, 155 |
| 5 | 95, 217, 19, 229, 155 |
| 19 | 19, 217, 19, 229, 31 |
| 31 | 1, 217, 1, 229, 31 |
| 1, 7, 1, 229, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 19 x 31 x 1 x 7 x 1 x 229 x 1 = 56650020
Therefore, the lowest common multiple of 570,434,228,916,620 is 56650020.
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.
570 x 434 x 228 x 916 x 620 = 32032187308800
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.
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
434 : 1, 2, 7, 14, 31, 62, 217, 434
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
916 : 1, 2, 4, 229, 458, 916
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 570,434,228,916,620, is 2.
Now, the common factors can be found like this.
570:2x 3x 5x 19
434:2x 7x 31
228:2x 2x 3x 19
916:2x 2x 229
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 5x 19x 31 = 282720
Therefore, the value for common factors is 282720.
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 = 32032187308800/(2x282720)
LCM = 32032187308800/565440
LCM = 56650020
Thus, we can understand that the LCM of 570,434,228,916,620 is 56650020.
