Given numbers are 770,416,290,836
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,416,290,836 is 88248160.
Find LCM of 770,416,290,836 with Prime Factorization
| 2 | 770, 416, 290, 836 |
| 2 | 385, 208, 145, 418 |
| 5 | 385, 104, 145, 209 |
| 11 | 77, 104, 29, 209 |
| 7, 104, 29, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 7 x 104 x 29 x 19 = 88248160
Therefore, the lowest common multiple of 770,416,290,836 is 88248160.
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.
770 x 416 x 290 x 836 = 77658380800
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
290 : 1, 2, 5, 10, 29, 58, 145, 290
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,416,290,836, is 2.
Now, the common factors can be found like this.
770:2x 5x 7x 11
416:2x 2x 2x 2x 2x 13
290:2x 5x 29
836:2x 2x 11x 19
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 5x 11 = 440
Therefore, the value for common factors is 440.
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 = 77658380800/(2x440)
LCM = 77658380800/880
LCM = 88248160
Thus, we can understand that the LCM of 770,416,290,836 is 88248160.
