Given numbers are 253,690,517,893
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,690,517,893 is 6777870.
Find LCM of 253,690,517,893 with Prime Factorization
| 11 | 253, 690, 517, 893 |
| 23 | 23, 690, 47, 893 |
| 47 | 1, 30, 47, 893 |
| 1, 30, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
11 x 23 x 47 x 1 x 30 x 1 x 19 = 6777870
Therefore, the lowest common multiple of 253,690,517,893 is 6777870.
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 690 x 517 x 893 = 80595652170
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
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
517 : 1, 11, 47, 517
893 : 1, 19, 47, 893
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,690,517,893, is 1.
Now, the common factors can be found like this.
253:11x 23
690:2x 3x 5x 23
517:11x 47
893:19x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 23x 47 = 11891
Therefore, the value for common factors is 11891.
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 = 80595652170/(1x11891)
LCM = 80595652170/11891
LCM = 6777870
Thus, we can understand that the LCM of 253,690,517,893 is 6777870.
