Find LCM of 639,720,466,493,203 with Prime Factorization
2 | 639, 720, 466, 493, 203 |
3 | 639, 360, 233, 493, 203 |
3 | 213, 120, 233, 493, 203 |
29 | 71, 40, 233, 493, 203 |
71, 40, 233, 17, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 29 x 71 x 40 x 233 x 17 x 7 = 41104722960
Therefore, the lowest common multiple of 639,720,466,493,203 is 41104722960.
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.
639 x 720 x 466 x 493 x 203 = 21456665385120
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.
639 : 1, 3, 9, 71, 213, 639
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
466 : 1, 2, 233, 466
493 : 1, 17, 29, 493
203 : 1, 7, 29, 203
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,720,466,493,203, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
720:2x 2x 2x 2x 3x 3x 5
466:2x 233
493:17x 29
203:7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 29 = 522
Therefore, the value for common factors is 522.
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 = 21456665385120/(1x522)
LCM = 21456665385120/522
LCM = 41104722960
Thus, we can understand that the LCM of 639,720,466,493,203 is 41104722960.
