Given numbers are 770,613,897,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,613,897,689 is 22439827410.
Find LCM of 770,613,897,689 with Prime Factorization
| 13 | 770, 613, 897, 689 |
| 770, 613, 69, 53 |
Multiply the prime numbers at the bottom and the left side.
13 x 770 x 613 x 69 x 53 = 22439827410
Therefore, the lowest common multiple of 770,613,897,689 is 22439827410.
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 613 x 897 x 689 = 291717756330
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
613 : 1, 613
897 : 1, 3, 13, 23, 39, 69, 299, 897
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,613,897,689, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
613:613
897:3x 13x 23
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 291717756330/(1x13)
LCM = 291717756330/13
LCM = 22439827410
Thus, we can understand that the LCM of 770,613,897,689 is 22439827410.
