Given numbers are 453,420,822,640,555
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 453,420,822,640,555 is 10287231360.
Find LCM of 453,420,822,640,555 with Prime Factorization
| 2 | 453, 420, 822, 640, 555 |
| 2 | 453, 210, 411, 320, 555 |
| 3 | 453, 105, 411, 160, 555 |
| 5 | 151, 35, 137, 160, 185 |
| 151, 7, 137, 32, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 151 x 7 x 137 x 32 x 37 = 10287231360
Therefore, the lowest common multiple of 453,420,822,640,555 is 10287231360.
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.
453 x 420 x 822 x 640 x 555 = 55551049344000
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.
453 : 1, 3, 151, 453
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
822 : 1, 2, 3, 6, 137, 274, 411, 822
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
555 : 1, 3, 5, 15, 37, 111, 185, 555
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 453,420,822,640,555, is 1.
Now, the common factors can be found like this.
453:3x 151
420:2x 2x 3x 5x 7
822:2x 3x 137
640:2x 2x 2x 2x 2x 2x 2x 5
555:3x 5x 37
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 3x 3x 3x 5x 5 = 5400
Therefore, the value for common factors is 5400.
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 = 55551049344000/(1x5400)
LCM = 55551049344000/5400
LCM = 10287231360
Thus, we can understand that the LCM of 453,420,822,640,555 is 10287231360.
