Given numbers are 770,197,869,442,615
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,197,869,442,615 is 325747752330.
Find LCM of 770,197,869,442,615 with Prime Factorization
| 2 | 770, 197, 869, 442, 615 |
| 5 | 385, 197, 869, 221, 615 |
| 11 | 77, 197, 869, 221, 123 |
| 7, 197, 79, 221, 123 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 7 x 197 x 79 x 221 x 123 = 325747752330
Therefore, the lowest common multiple of 770,197,869,442,615 is 325747752330.
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 197 x 869 x 442 x 615 = 35832252756300
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
197 : 1, 197
869 : 1, 11, 79, 869
442 : 1, 2, 13, 17, 26, 34, 221, 442
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,197,869,442,615, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
197:197
869:11x 79
442:2x 13x 17
615:3x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 35832252756300/(1x110)
LCM = 35832252756300/110
LCM = 325747752330
Thus, we can understand that the LCM of 770,197,869,442,615 is 325747752330.
