Given numbers are 770,756,691,150
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,756,691,150 is 143658900.
Find LCM of 770,756,691,150 with Prime Factorization
| 2 | 770, 756, 691, 150 |
| 3 | 385, 378, 691, 75 |
| 5 | 385, 126, 691, 25 |
| 7 | 77, 126, 691, 5 |
| 11, 18, 691, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 11 x 18 x 691 x 5 = 143658900
Therefore, the lowest common multiple of 770,756,691,150 is 143658900.
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 756 x 691 x 150 = 60336738000
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
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
691 : 1, 691
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,756,691,150, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
756:2x 2x 3x 3x 3x 7
691:691
150:2x 3x 5x 5
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 3x 5x 7 = 420
Therefore, the value for common factors is 420.
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 = 60336738000/(1x420)
LCM = 60336738000/420
LCM = 143658900
Thus, we can understand that the LCM of 770,756,691,150 is 143658900.
