Find LCM of 420,532,113,768,312 with Prime Factorization
2 | 420, 532, 113, 768, 312 |
2 | 210, 266, 113, 384, 156 |
2 | 105, 133, 113, 192, 78 |
3 | 105, 133, 113, 96, 39 |
7 | 35, 133, 113, 32, 13 |
5, 19, 113, 32, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 5 x 19 x 113 x 32 x 13 = 750247680
Therefore, the lowest common multiple of 420,532,113,768,312 is 750247680.
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.
420 x 532 x 113 x 768 x 312 = 6049997291520
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.
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
113 : 1, 113
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,532,113,768,312, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
532:2x 2x 7x 19
113:113
768:2x 2x 2x 2x 2x 2x 2x 2x 3
312:2x 2x 2x 3x 13
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 2x 2x 3x 3x 7 = 8064
Therefore, the value for common factors is 8064.
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 = 6049997291520/(1x8064)
LCM = 6049997291520/8064
LCM = 750247680
Thus, we can understand that the LCM of 420,532,113,768,312 is 750247680.
