Given numbers are 839,561,702,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 839,561,702,154 is 770972202.
Find LCM of 839,561,702,154 with Prime Factorization
| 2 | 839, 561, 702, 154 |
| 3 | 839, 561, 351, 77 |
| 11 | 839, 187, 117, 77 |
| 839, 17, 117, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 839 x 17 x 117 x 7 = 770972202
Therefore, the lowest common multiple of 839,561,702,154 is 770972202.
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.
839 x 561 x 702 x 154 = 50884165332
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.
839 : 1, 839
561 : 1, 3, 11, 17, 33, 51, 187, 561
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 839,561,702,154, is 1.
Now, the common factors can be found like this.
839:839
561:3x 11x 17
702:2x 3x 3x 3x 13
154:2x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 50884165332/(1x66)
LCM = 50884165332/66
LCM = 770972202
Thus, we can understand that the LCM of 839,561,702,154 is 770972202.
