Given numbers are 658,428,749,612
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,428,749,612 is 21544236.
Find LCM of 658,428,749,612 with Prime Factorization
| 2 | 658, 428, 749, 612 |
| 2 | 329, 214, 749, 306 |
| 7 | 329, 107, 749, 153 |
| 107 | 47, 107, 107, 153 |
| 47, 1, 1, 153 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 107 x 47 x 1 x 1 x 153 = 21544236
Therefore, the lowest common multiple of 658,428,749,612 is 21544236.
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.
658 x 428 x 749 x 612 = 129093062112
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
428 : 1, 2, 4, 107, 214, 428
749 : 1, 7, 107, 749
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,428,749,612, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
428:2x 2x 107
749:7x 107
612:2x 2x 3x 3x 17
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 7x 107 = 5992
Therefore, the value for common factors is 5992.
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 = 129093062112/(1x5992)
LCM = 129093062112/5992
LCM = 21544236
Thus, we can understand that the LCM of 658,428,749,612 is 21544236.
