Given numbers are 452,855,692,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 452,855,692,988 is 869148540.
Find LCM of 452,855,692,988 with Prime Factorization
| 2 | 452, 855, 692, 988 |
| 2 | 226, 855, 346, 494 |
| 19 | 113, 855, 173, 247 |
| 113, 45, 173, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 113 x 45 x 173 x 13 = 869148540
Therefore, the lowest common multiple of 452,855,692,988 is 869148540.
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.
452 x 855 x 692 x 988 = 264221156160
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.
452 : 1, 2, 4, 113, 226, 452
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
692 : 1, 2, 4, 173, 346, 692
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 452,855,692,988, is 1.
Now, the common factors can be found like this.
452:2x 2x 113
855:3x 3x 5x 19
692:2x 2x 173
988:2x 2x 13x 19
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 19 = 304
Therefore, the value for common factors is 304.
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 = 264221156160/(1x304)
LCM = 264221156160/304
LCM = 869148540
Thus, we can understand that the LCM of 452,855,692,988 is 869148540.
