Given numbers are 253,458,616,722,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,458,616,722,421 is 493098099032.
Find LCM of 253,458,616,722,421 with Prime Factorization
| 2 | 253, 458, 616, 722, 421 |
| 11 | 253, 229, 308, 361, 421 |
| 23, 229, 28, 361, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 23 x 229 x 28 x 361 x 421 = 493098099032
Therefore, the lowest common multiple of 253,458,616,722,421 is 493098099032.
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 458 x 616 x 722 x 421 = 21696316357408
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
458 : 1, 2, 229, 458
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
722 : 1, 2, 19, 38, 361, 722
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,458,616,722,421, is 1.
Now, the common factors can be found like this.
253:11x 23
458:2x 229
616:2x 2x 2x 7x 11
722:2x 19x 19
421:421
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 11 = 44
Therefore, the value for common factors is 44.
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 = 21696316357408/(1x44)
LCM = 21696316357408/44
LCM = 493098099032
Thus, we can understand that the LCM of 253,458,616,722,421 is 493098099032.
