Given numbers are 460,690,690,542
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 460,690,690,542 is 373980.
Find LCM of 460,690,690,542 with Prime Factorization
2 | 460, 690, 690, 542 |
3 | 230, 345, 345, 271 |
5 | 230, 115, 115, 271 |
23 | 46, 23, 23, 271 |
2, 1, 1, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 2 x 1 x 1 x 271 = 373980
Therefore, the lowest common multiple of 460,690,690,542 is 373980.
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.
460 x 690 x 690 x 542 = 118701252000
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.
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
542 : 1, 2, 271, 542
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 460,690,690,542, is 2.
Now, the common factors can be found like this.
460:2x 2x 5x 23
690:2x 3x 5x 23
690:2x 3x 5x 23
542:2x 271
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 3x 5x 5x 23x 23 = 158700
Therefore, the value for common factors is 158700.
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 = 118701252000/(2x158700)
LCM = 118701252000/317400
LCM = 373980
Thus, we can understand that the LCM of 460,690,690,542 is 373980.
