Given numbers are 551,209,957,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,209,957,220 is 363660.
Find LCM of 551,209,957,220 with Prime Factorization
| 11 | 551, 209, 957, 220 |
| 19 | 551, 19, 87, 20 |
| 29 | 29, 1, 87, 20 |
| 1, 1, 3, 20 |
Multiply the prime numbers at the bottom and the left side.
11 x 19 x 29 x 1 x 1 x 3 x 20 = 363660
Therefore, the lowest common multiple of 551,209,957,220 is 363660.
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.
551 x 209 x 957 x 220 = 24245575860
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.
551 : 1, 19, 29, 551
209 : 1, 11, 19, 209
957 : 1, 3, 11, 29, 33, 87, 319, 957
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,209,957,220, is 1.
Now, the common factors can be found like this.
551:19x 29
209:11x 19
957:3x 11x 29
220:2x 2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11x 19x 29 = 66671
Therefore, the value for common factors is 66671.
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 = 24245575860/(1x66671)
LCM = 24245575860/66671
LCM = 363660
Thus, we can understand that the LCM of 551,209,957,220 is 363660.
