Given numbers are 318,140,680,946,419
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 318,140,680,946,419 is 149995849080.
Find LCM of 318,140,680,946,419 with Prime Factorization
| 2 | 318, 140, 680, 946, 419 |
| 2 | 159, 70, 340, 473, 419 |
| 5 | 159, 35, 170, 473, 419 |
| 159, 7, 34, 473, 419 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 159 x 7 x 34 x 473 x 419 = 149995849080
Therefore, the lowest common multiple of 318,140,680,946,419 is 149995849080.
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.
318 x 140 x 680 x 946 x 419 = 11999667926400
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.
318 : 1, 2, 3, 6, 53, 106, 159, 318
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
946 : 1, 2, 11, 22, 43, 86, 473, 946
419 : 1, 419
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,140,680,946,419, is 1.
Now, the common factors can be found like this.
318:2x 3x 53
140:2x 2x 5x 7
680:2x 2x 2x 5x 17
946:2x 11x 43
419:419
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 5 = 80
Therefore, the value for common factors is 80.
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 = 11999667926400/(1x80)
LCM = 11999667926400/80
LCM = 149995849080
Thus, we can understand that the LCM of 318,140,680,946,419 is 149995849080.
