Given numbers are 274,689,423,286
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 274,689,423,286 is 878421258.
Find LCM of 274,689,423,286 with Prime Factorization
2 | 274, 689, 423, 286 |
13 | 137, 689, 423, 143 |
137, 53, 423, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 137 x 53 x 423 x 11 = 878421258
Therefore, the lowest common multiple of 274,689,423,286 is 878421258.
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.
274 x 689 x 423 x 286 = 22838952708
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.
274 : 1, 2, 137, 274
689 : 1, 13, 53, 689
423 : 1, 3, 9, 47, 141, 423
286 : 1, 2, 11, 13, 22, 26, 143, 286
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 274,689,423,286, is 1.
Now, the common factors can be found like this.
274:2x 137
689:13x 53
423:3x 3x 47
286:2x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 22838952708/(1x26)
LCM = 22838952708/26
LCM = 878421258
Thus, we can understand that the LCM of 274,689,423,286 is 878421258.
