Given numbers are 147,203,691,667,940
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 147,203,691,667,940 is 63686747460.
Find LCM of 147,203,691,667,940 with Prime Factorization
| 7 | 147, 203, 691, 667, 940 |
| 29 | 21, 29, 691, 667, 940 |
| 21, 1, 691, 23, 940 |
Multiply the prime numbers at the bottom and the left side.
7 x 29 x 21 x 1 x 691 x 23 x 940 = 63686747460
Therefore, the lowest common multiple of 147,203,691,667,940 is 63686747460.
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.
147 x 203 x 691 x 667 x 940 = 12928409734380
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.
147 : 1, 3, 7, 21, 49, 147
203 : 1, 7, 29, 203
691 : 1, 691
667 : 1, 23, 29, 667
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 147,203,691,667,940, is 1.
Now, the common factors can be found like this.
147:3x 7x 7
203:7x 29
691:691
667:23x 29
940:2x 2x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 29 = 203
Therefore, the value for common factors is 203.
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 = 12928409734380/(1x203)
LCM = 12928409734380/203
LCM = 63686747460
Thus, we can understand that the LCM of 147,203,691,667,940 is 63686747460.
