Given numbers are 986,452,868,663,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 986,452,868,663,421 is 793947509628.
Find LCM of 986,452,868,663,421 with Prime Factorization
2 | 986, 452, 868, 663, 421 |
2 | 493, 226, 434, 663, 421 |
17 | 493, 113, 217, 663, 421 |
29, 113, 217, 39, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 29 x 113 x 217 x 39 x 421 = 793947509628
Therefore, the lowest common multiple of 986,452,868,663,421 is 793947509628.
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.
986 x 452 x 868 x 663 x 421 = 107976861309408
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
452 : 1, 2, 4, 113, 226, 452
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
663 : 1, 3, 13, 17, 39, 51, 221, 663
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,452,868,663,421, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
452:2x 2x 113
868:2x 2x 7x 31
663:3x 13x 17
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 2x 17 = 136
Therefore, the value for common factors is 136.
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 = 107976861309408/(1x136)
LCM = 107976861309408/136
LCM = 793947509628
Thus, we can understand that the LCM of 986,452,868,663,421 is 793947509628.
