The LCM of 750,680,144,639 is 21726000.
Find LCM of 750,680,144,639 with Prime Factorization
| 2 | 750, 680, 144, 639 |
| 2 | 375, 340, 72, 639 |
| 2 | 375, 170, 36, 639 |
| 3 | 375, 85, 18, 639 |
| 3 | 125, 85, 6, 213 |
| 5 | 125, 85, 2, 71 |
| 25, 17, 2, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 25 x 17 x 2 x 71 = 21726000
Therefore, the lowest common multiple of 750,680,144,639 is 21726000.
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.
750 x 680 x 144 x 639 = 46928160000
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.
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 750,680,144,639, is 1.
Now, the common factors can be found like this.
750:2x 3x 5x 5x 5
680:2x 2x 2x 5x 17
144:2x 2x 2x 2x 3x 3
639:3x 3x 71
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 3x 3x 3x 5 = 2160
Therefore, the value for common factors is 2160.
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 = 46928160000/(1x2160)
LCM = 46928160000/2160
LCM = 21726000
Thus, we can understand that the LCM of 750,680,144,639 is 21726000.
