Given numbers are 640,649,998,452
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 640,649,998,452 is 23420904320.
Find LCM of 640,649,998,452 with Prime Factorization
2 | 640, 649, 998, 452 |
2 | 320, 649, 499, 226 |
160, 649, 499, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 160 x 649 x 499 x 113 = 23420904320
Therefore, the lowest common multiple of 640,649,998,452 is 23420904320.
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.
640 x 649 x 998 x 452 = 187367234560
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
649 : 1, 11, 59, 649
998 : 1, 2, 499, 998
452 : 1, 2, 4, 113, 226, 452
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,649,998,452, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
649:11x 59
998:2x 499
452:2x 2x 113
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 2 = 8
Therefore, the value for common factors is 8.
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 = 187367234560/(1x8)
LCM = 187367234560/8
LCM = 23420904320
Thus, we can understand that the LCM of 640,649,998,452 is 23420904320.
