Find LCM of 440,655,470,369,423 with Prime Factorization
| 2 | 440, 655, 470, 369, 423 |
| 3 | 220, 655, 235, 369, 423 |
| 3 | 220, 655, 235, 123, 141 |
| 5 | 220, 655, 235, 41, 47 |
| 47 | 44, 131, 47, 41, 47 |
| 44, 131, 1, 41, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 47 x 44 x 131 x 1 x 41 x 1 = 999650520
Therefore, the lowest common multiple of 440,655,470,369,423 is 999650520.
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.
440 x 655 x 470 x 369 x 423 = 21142608498000
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.
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
655 : 1, 5, 131, 655
470 : 1, 2, 5, 10, 47, 94, 235, 470
369 : 1, 3, 9, 41, 123, 369
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,655,470,369,423, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
655:5x 131
470:2x 5x 47
369:3x 3x 41
423:3x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 5x 47 = 21150
Therefore, the value for common factors is 21150.
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 = 21142608498000/(1x21150)
LCM = 21142608498000/21150
LCM = 999650520
Thus, we can understand that the LCM of 440,655,470,369,423 is 999650520.
