The LCM of 620,627,225,144 is 23324400.
Find LCM of 620,627,225,144 with Prime Factorization
2 | 620, 627, 225, 144 |
2 | 310, 627, 225, 72 |
3 | 155, 627, 225, 36 |
3 | 155, 209, 75, 12 |
5 | 155, 209, 25, 4 |
31, 209, 5, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 31 x 209 x 5 x 4 = 23324400
Therefore, the lowest common multiple of 620,627,225,144 is 23324400.
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.
620 x 627 x 225 x 144 = 12595176000
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
627 : 1, 3, 11, 19, 33, 57, 209, 627
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,627,225,144, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
627:3x 11x 19
225:3x 3x 5x 5
144:2x 2x 2x 2x 3x 3
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 3x 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 12595176000/(1x540)
LCM = 12595176000/540
LCM = 23324400
Thus, we can understand that the LCM of 620,627,225,144 is 23324400.
