Given numbers are 762,748,988,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 762,748,988,988 is 70392036.
Find LCM of 762,748,988,988 with Prime Factorization
| 2 | 762, 748, 988, 988 |
| 2 | 381, 374, 494, 494 |
| 13 | 381, 187, 247, 247 |
| 19 | 381, 187, 19, 19 |
| 381, 187, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 381 x 187 x 1 x 1 = 70392036
Therefore, the lowest common multiple of 762,748,988,988 is 70392036.
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.
762 x 748 x 988 x 988 = 556378652544
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,748,988,988, is 2.
Now, the common factors can be found like this.
762:2x 3x 127
748:2x 2x 11x 17
988:2x 2x 13x 19
988:2x 2x 13x 19
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 13x 19 = 3952
Therefore, the value for common factors is 3952.
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 = 556378652544/(2x3952)
LCM = 556378652544/7904
LCM = 70392036
Thus, we can understand that the LCM of 762,748,988,988 is 70392036.
