Find LCM of 487,390,428,684,672 with Prime Factorization
2 | 487, 390, 428, 684, 672 |
2 | 487, 195, 214, 342, 336 |
3 | 487, 195, 107, 171, 168 |
487, 65, 107, 57, 56 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 487 x 65 x 107 x 57 x 56 = 129738903840
Therefore, the lowest common multiple of 487,390,428,684,672 is 129738903840.
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.
487 x 390 x 428 x 684 x 672 = 37364804305920
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.
487 : 1, 487
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
428 : 1, 2, 4, 107, 214, 428
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,390,428,684,672, is 1.
Now, the common factors can be found like this.
487:487
390:2x 3x 5x 13
428:2x 2x 107
684:2x 2x 3x 3x 19
672:2x 2x 2x 2x 2x 3x 7
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 3 = 288
Therefore, the value for common factors is 288.
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 = 37364804305920/(1x288)
LCM = 37364804305920/288
LCM = 129738903840
Thus, we can understand that the LCM of 487,390,428,684,672 is 129738903840.
