Given numbers are 253,781,488,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,781,488,663 is 5811820872.
Find LCM of 253,781,488,663 with Prime Factorization
| 11 | 253, 781, 488, 663 |
| 23, 71, 488, 663 |
Multiply the prime numbers at the bottom and the left side.
11 x 23 x 71 x 488 x 663 = 5811820872
Therefore, the lowest common multiple of 253,781,488,663 is 5811820872.
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.
253 x 781 x 488 x 663 = 63930029592
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.
253 : 1, 11, 23, 253
781 : 1, 11, 71, 781
488 : 1, 2, 4, 8, 61, 122, 244, 488
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,781,488,663, is 1.
Now, the common factors can be found like this.
253:11x 23
781:11x 71
488:2x 2x 2x 61
663:3x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 63930029592/(1x11)
LCM = 63930029592/11
LCM = 5811820872
Thus, we can understand that the LCM of 253,781,488,663 is 5811820872.
