Given numbers are 724,988,436,298,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,988,436,298,220 is 159739005140.
Find LCM of 724,988,436,298,220 with Prime Factorization
| 2 | 724, 988, 436, 298, 220 |
| 2 | 362, 494, 218, 149, 110 |
| 181, 247, 109, 149, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 181 x 247 x 109 x 149 x 55 = 159739005140
Therefore, the lowest common multiple of 724,988,436,298,220 is 159739005140.
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.
724 x 988 x 436 x 298 x 220 = 20446592657920
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.
724 : 1, 2, 4, 181, 362, 724
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
436 : 1, 2, 4, 109, 218, 436
298 : 1, 2, 149, 298
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,988,436,298,220, is 2.
Now, the common factors can be found like this.
724:2x 2x 181
988:2x 2x 13x 19
436:2x 2x 109
298:2x 149
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.
2x 2x 2x 2x 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 20446592657920/(2x64)
LCM = 20446592657920/128
LCM = 159739005140
Thus, we can understand that the LCM of 724,988,436,298,220 is 159739005140.
