Given numbers are 766,890,680,754,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,890,680,754,154 is 672867835640.
Find LCM of 766,890,680,754,154 with Prime Factorization
| 2 | 766, 890, 680, 754, 154 |
| 5 | 383, 445, 340, 377, 77 |
| 383, 89, 68, 377, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 383 x 89 x 68 x 377 x 77 = 672867835640
Therefore, the lowest common multiple of 766,890,680,754,154 is 672867835640.
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.
766 x 890 x 680 x 754 x 154 = 53829426851200
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.
766 : 1, 2, 383, 766
890 : 1, 2, 5, 10, 89, 178, 445, 890
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
754 : 1, 2, 13, 26, 29, 58, 377, 754
154 : 1, 2, 7, 11, 14, 22, 77, 154
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,890,680,754,154, is 2.
Now, the common factors can be found like this.
766:2x 383
890:2x 5x 89
680:2x 2x 2x 5x 17
754:2x 13x 29
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 2x 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 53829426851200/(2x40)
LCM = 53829426851200/80
LCM = 672867835640
Thus, we can understand that the LCM of 766,890,680,754,154 is 672867835640.
