Given numbers are 970,161,143,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 970,161,143,690 is 66996930.
Find LCM of 970,161,143,690 with Prime Factorization
2 | 970, 161, 143, 690 |
5 | 485, 161, 143, 345 |
23 | 97, 161, 143, 69 |
97, 7, 143, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 97 x 7 x 143 x 3 = 66996930
Therefore, the lowest common multiple of 970,161,143,690 is 66996930.
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.
970 x 161 x 143 x 690 = 15409293900
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.
970 : 1, 2, 5, 10, 97, 194, 485, 970
161 : 1, 7, 23, 161
143 : 1, 11, 13, 143
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 970,161,143,690, is 1.
Now, the common factors can be found like this.
970:2x 5x 97
161:7x 23
143:11x 13
690:2x 3x 5x 23
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 23 = 230
Therefore, the value for common factors is 230.
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 = 15409293900/(1x230)
LCM = 15409293900/230
LCM = 66996930
Thus, we can understand that the LCM of 970,161,143,690 is 66996930.
