Find LCM of 223,420,744,434,579 with Prime Factorization
| 2 | 223, 420, 744, 434, 579 |
| 2 | 223, 210, 372, 217, 579 |
| 3 | 223, 105, 186, 217, 579 |
| 7 | 223, 35, 62, 217, 193 |
| 31 | 223, 5, 62, 31, 193 |
| 223, 5, 2, 1, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 31 x 223 x 5 x 2 x 1 x 193 = 1120735560
Therefore, the lowest common multiple of 223,420,744,434,579 is 1120735560.
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.
223 x 420 x 744 x 434 x 579 = 17510372389440
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.
223 : 1, 223
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
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
434 : 1, 2, 7, 14, 31, 62, 217, 434
579 : 1, 3, 193, 579
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 223,420,744,434,579, is 1.
Now, the common factors can be found like this.
223:223
420:2x 2x 3x 5x 7
744:2x 2x 2x 3x 31
434:2x 7x 31
579:3x 193
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 3x 3x 7x 31 = 15624
Therefore, the value for common factors is 15624.
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 = 17510372389440/(1x15624)
LCM = 17510372389440/15624
LCM = 1120735560
Thus, we can understand that the LCM of 223,420,744,434,579 is 1120735560.
