Find LCM of 144,783,424,420,421 with Prime Factorization
2 | 144, 783, 424, 420, 421 |
2 | 72, 783, 212, 210, 421 |
2 | 36, 783, 106, 105, 421 |
3 | 18, 783, 53, 105, 421 |
3 | 6, 261, 53, 35, 421 |
2, 87, 53, 35, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 2 x 87 x 53 x 35 x 421 = 9783804240
Therefore, the lowest common multiple of 144,783,424,420,421 is 9783804240.
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.
144 x 783 x 424 x 420 x 421 = 8453206863360
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.
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
783 : 1, 3, 9, 27, 29, 87, 261, 783
424 : 1, 2, 4, 8, 53, 106, 212, 424
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
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 144,783,424,420,421, is 1.
Now, the common factors can be found like this.
144:2x 2x 2x 2x 3x 3
783:3x 3x 3x 29
424:2x 2x 2x 53
420:2x 2x 3x 5x 7
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 2x 2x 3x 3x 3 = 864
Therefore, the value for common factors is 864.
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 = 8453206863360/(1x864)
LCM = 8453206863360/864
LCM = 9783804240
Thus, we can understand that the LCM of 144,783,424,420,421 is 9783804240.
