Given numbers are 770,217,434,772
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,217,434,772 is 9213820.
Find LCM of 770,217,434,772 with Prime Factorization
2 | 770, 217, 434, 772 |
7 | 385, 217, 217, 386 |
31 | 55, 31, 31, 386 |
55, 1, 1, 386 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 31 x 55 x 1 x 1 x 386 = 9213820
Therefore, the lowest common multiple of 770,217,434,772 is 9213820.
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 217 x 434 x 772 = 55983170320
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
217 : 1, 7, 31, 217
434 : 1, 2, 7, 14, 31, 62, 217, 434
772 : 1, 2, 4, 193, 386, 772
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,217,434,772, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
217:7x 31
434:2x 7x 31
772:2x 2x 193
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 7x 7x 31 = 6076
Therefore, the value for common factors is 6076.
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 = 55983170320/(1x6076)
LCM = 55983170320/6076
LCM = 9213820
Thus, we can understand that the LCM of 770,217,434,772 is 9213820.
