Given numbers are 556,209,207,146,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,209,207,146,720 is 35119172880.
Find LCM of 556,209,207,146,720 with Prime Factorization
| 2 | 556, 209, 207, 146, 720 |
| 2 | 278, 209, 207, 73, 360 |
| 3 | 139, 209, 207, 73, 180 |
| 3 | 139, 209, 69, 73, 60 |
| 139, 209, 23, 73, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 139 x 209 x 23 x 73 x 20 = 35119172880
Therefore, the lowest common multiple of 556,209,207,146,720 is 35119172880.
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.
556 x 209 x 207 x 146 x 720 = 2528580447360
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.
556 : 1, 2, 4, 139, 278, 556
209 : 1, 11, 19, 209
207 : 1, 3, 9, 23, 69, 207
146 : 1, 2, 73, 146
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 556,209,207,146,720, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
209:11x 19
207:3x 3x 23
146:2x 73
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 2528580447360/(1x72)
LCM = 2528580447360/72
LCM = 35119172880
Thus, we can understand that the LCM of 556,209,207,146,720 is 35119172880.
