Find LCM of 639,407,216,740,360 with Prime Factorization
2 | 639, 407, 216, 740, 360 |
2 | 639, 407, 108, 370, 180 |
2 | 639, 407, 54, 185, 90 |
3 | 639, 407, 27, 185, 45 |
3 | 213, 407, 9, 185, 15 |
5 | 71, 407, 3, 185, 5 |
37 | 71, 407, 3, 37, 1 |
71, 11, 3, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 37 x 71 x 11 x 3 x 1 x 1 = 31208760
Therefore, the lowest common multiple of 639,407,216,740,360 is 31208760.
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 407 x 216 x 740 x 360 = 14965224595200
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
407 : 1, 11, 37, 407
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,407,216,740,360, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
407:11x 37
216:2x 2x 2x 3x 3x 3
740:2x 2x 5x 37
360:2x 2x 2x 3x 3x 5
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 3x 3x 3x 5x 37 = 479520
Therefore, the value for common factors is 479520.
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 = 14965224595200/(1x479520)
LCM = 14965224595200/479520
LCM = 31208760
Thus, we can understand that the LCM of 639,407,216,740,360 is 31208760.
