Find LCM of 462,220,891,991,724 with Prime Factorization
| 2 | 462, 220, 891, 991, 724 |
| 2 | 231, 110, 891, 991, 362 |
| 3 | 231, 55, 891, 991, 181 |
| 11 | 77, 55, 297, 991, 181 |
| 7, 5, 27, 991, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 7 x 5 x 27 x 991 x 181 = 22374738540
Therefore, the lowest common multiple of 462,220,891,991,724 is 22374738540.
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.
462 x 220 x 891 x 991 x 724 = 64976240720160
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.
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
991 : 1, 991
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 462,220,891,991,724, is 1.
Now, the common factors can be found like this.
462:2x 3x 7x 11
220:2x 2x 5x 11
891:3x 3x 3x 3x 11
991:991
724:2x 2x 181
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 11x 11 = 2904
Therefore, the value for common factors is 2904.
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 = 64976240720160/(1x2904)
LCM = 64976240720160/2904
LCM = 22374738540
Thus, we can understand that the LCM of 462,220,891,991,724 is 22374738540.
