Given numbers are 647,744,471,604
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,744,471,604 is 11411791176.
Find LCM of 647,744,471,604 with Prime Factorization
| 2 | 647, 744, 471, 604 |
| 2 | 647, 372, 471, 302 |
| 3 | 647, 186, 471, 151 |
| 647, 62, 157, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 647 x 62 x 157 x 151 = 11411791176
Therefore, the lowest common multiple of 647,744,471,604 is 11411791176.
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.
647 x 744 x 471 x 604 = 136941494112
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.
647 : 1, 647
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
471 : 1, 3, 157, 471
604 : 1, 2, 4, 151, 302, 604
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,744,471,604, is 1.
Now, the common factors can be found like this.
647:647
744:2x 2x 2x 3x 31
471:3x 157
604:2x 2x 151
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 3 = 12
Therefore, the value for common factors is 12.
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 = 136941494112/(1x12)
LCM = 136941494112/12
LCM = 11411791176
Thus, we can understand that the LCM of 647,744,471,604 is 11411791176.
