Find LCM of 639,440,600,737,871 with Prime Factorization
| 2 | 639, 440, 600, 737, 871 |
| 2 | 639, 220, 300, 737, 871 |
| 2 | 639, 110, 150, 737, 871 |
| 3 | 639, 55, 75, 737, 871 |
| 5 | 213, 55, 25, 737, 871 |
| 11 | 213, 11, 5, 737, 871 |
| 67 | 213, 1, 5, 67, 871 |
| 213, 1, 5, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 11 x 67 x 213 x 1 x 5 x 1 x 13 = 1224451800
Therefore, the lowest common multiple of 639,440,600,737,871 is 1224451800.
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.
639 x 440 x 600 x 737 x 871 = 108290517192000
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.
639 : 1, 3, 9, 71, 213, 639
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
737 : 1, 11, 67, 737
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,440,600,737,871, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
440:2x 2x 2x 5x 11
600:2x 2x 2x 3x 5x 5
737:11x 67
871:13x 67
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 5x 11x 67 = 88440
Therefore, the value for common factors is 88440.
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 = 108290517192000/(1x88440)
LCM = 108290517192000/88440
LCM = 1224451800
Thus, we can understand that the LCM of 639,440,600,737,871 is 1224451800.
