Find LCM of 387,360,703,288,421 with Prime Factorization
2 | 387, 360, 703, 288, 421 |
2 | 387, 180, 703, 144, 421 |
2 | 387, 90, 703, 72, 421 |
3 | 387, 45, 703, 36, 421 |
3 | 129, 15, 703, 12, 421 |
43, 5, 703, 4, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 43 x 5 x 703 x 4 x 421 = 18326028960
Therefore, the lowest common multiple of 387,360,703,288,421 is 18326028960.
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.
387 x 360 x 703 x 288 x 421 = 11875266766080
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.
387 : 1, 3, 9, 43, 129, 387
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
703 : 1, 19, 37, 703
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,360,703,288,421, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
360:2x 2x 2x 3x 3x 5
703:19x 37
288:2x 2x 2x 2x 2x 3x 3
421:421
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 3x 3 = 648
Therefore, the value for common factors is 648.
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 = 11875266766080/(1x648)
LCM = 11875266766080/648
LCM = 18326028960
Thus, we can understand that the LCM of 387,360,703,288,421 is 18326028960.
