Find LCM of 221,231,742,744,968 with Prime Factorization
2 | 221, 231, 742, 744, 968 |
2 | 221, 231, 371, 372, 484 |
2 | 221, 231, 371, 186, 242 |
3 | 221, 231, 371, 93, 121 |
7 | 221, 77, 371, 31, 121 |
11 | 221, 11, 53, 31, 121 |
221, 1, 53, 31, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 11 x 221 x 1 x 53 x 31 x 11 = 7381157784
Therefore, the lowest common multiple of 221,231,742,744,968 is 7381157784.
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 231 x 742 x 744 x 968 = 27280759169664
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
231 : 1, 3, 7, 11, 21, 33, 77, 231
742 : 1, 2, 7, 14, 53, 106, 371, 742
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,231,742,744,968, is 1.
Now, the common factors can be found like this.
221:13x 17
231:3x 7x 11
742:2x 7x 53
744:2x 2x 2x 3x 31
968:2x 2x 2x 11x 11
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 7x 11 = 3696
Therefore, the value for common factors is 3696.
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 = 27280759169664/(1x3696)
LCM = 27280759169664/3696
LCM = 7381157784
Thus, we can understand that the LCM of 221,231,742,744,968 is 7381157784.
