The LCM of 507,291,400,720 is 59014800.
Find LCM of 507,291,400,720 with Prime Factorization
| 2 | 507, 291, 400, 720 |
| 2 | 507, 291, 200, 360 |
| 2 | 507, 291, 100, 180 |
| 2 | 507, 291, 50, 90 |
| 3 | 507, 291, 25, 45 |
| 5 | 169, 97, 25, 15 |
| 169, 97, 5, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 169 x 97 x 5 x 3 = 59014800
Therefore, the lowest common multiple of 507,291,400,720 is 59014800.
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.
507 x 291 x 400 x 720 = 42490656000
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.
507 : 1, 3, 13, 39, 169, 507
291 : 1, 3, 97, 291
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 507,291,400,720, is 1.
Now, the common factors can be found like this.
507:3x 13x 13
291:3x 97
400:2x 2x 2x 2x 5x 5
720:2x 2x 2x 2x 3x 3x 5
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 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 42490656000/(1x720)
LCM = 42490656000/720
LCM = 59014800
Thus, we can understand that the LCM of 507,291,400,720 is 59014800.
