Given numbers are 221,850,748,731,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,850,748,731,947 is 9899275100.
Find LCM of 221,850,748,731,947 with Prime Factorization
| 2 | 221, 850, 748, 731, 947 |
| 17 | 221, 425, 374, 731, 947 |
| 13, 25, 22, 43, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 13 x 25 x 22 x 43 x 947 = 9899275100
Therefore, the lowest common multiple of 221,850,748,731,947 is 9899275100.
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.
221 x 850 x 748 x 731 x 947 = 97270277132600
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.
221 : 1, 13, 17, 221
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
731 : 1, 17, 43, 731
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,850,748,731,947, is 1.
Now, the common factors can be found like this.
221:13x 17
850:2x 5x 5x 17
748:2x 2x 11x 17
731:17x 43
947:947
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 17x 17 = 9826
Therefore, the value for common factors is 9826.
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 = 97270277132600/(1x9826)
LCM = 97270277132600/9826
LCM = 9899275100
Thus, we can understand that the LCM of 221,850,748,731,947 is 9899275100.
