Given numbers are 631,981,690,763
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,981,690,763 is 996607710.
Find LCM of 631,981,690,763 with Prime Factorization
3 | 631, 981, 690, 763 |
109 | 631, 327, 230, 763 |
631, 3, 230, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 109 x 631 x 3 x 230 x 7 = 996607710
Therefore, the lowest common multiple of 631,981,690,763 is 996607710.
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.
631 x 981 x 690 x 763 = 325890721170
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.
631 : 1, 631
981 : 1, 3, 9, 109, 327, 981
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
763 : 1, 7, 109, 763
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,981,690,763, is 1.
Now, the common factors can be found like this.
631:631
981:3x 3x 109
690:2x 3x 5x 23
763:7x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 109 = 327
Therefore, the value for common factors is 327.
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 = 325890721170/(1x327)
LCM = 325890721170/327
LCM = 996607710
Thus, we can understand that the LCM of 631,981,690,763 is 996607710.
