Given numbers are 428,527,899,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,527,899,680 is 65411240.
Find LCM of 428,527,899,680 with Prime Factorization
2 | 428, 527, 899, 680 |
2 | 214, 527, 899, 340 |
17 | 107, 527, 899, 170 |
31 | 107, 31, 899, 10 |
107, 1, 29, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 31 x 107 x 1 x 29 x 10 = 65411240
Therefore, the lowest common multiple of 428,527,899,680 is 65411240.
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.
428 x 527 x 899 x 680 = 137886893920
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.
428 : 1, 2, 4, 107, 214, 428
527 : 1, 17, 31, 527
899 : 1, 29, 31, 899
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,527,899,680, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
527:17x 31
899:29x 31
680:2x 2x 2x 5x 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 17x 31 = 2108
Therefore, the value for common factors is 2108.
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 = 137886893920/(1x2108)
LCM = 137886893920/2108
LCM = 65411240
Thus, we can understand that the LCM of 428,527,899,680 is 65411240.
