Given numbers are 620,781,585,711
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,781,585,711 is 4475645460.
Find LCM of 620,781,585,711 with Prime Factorization
3 | 620, 781, 585, 711 |
3 | 620, 781, 195, 237 |
5 | 620, 781, 65, 79 |
124, 781, 13, 79 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 124 x 781 x 13 x 79 = 4475645460
Therefore, the lowest common multiple of 620,781,585,711 is 4475645460.
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.
620 x 781 x 585 x 711 = 201404045700
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
781 : 1, 11, 71, 781
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
711 : 1, 3, 9, 79, 237, 711
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,781,585,711, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
781:11x 71
585:3x 3x 5x 13
711:3x 3x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5 = 45
Therefore, the value for common factors is 45.
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 = 201404045700/(1x45)
LCM = 201404045700/45
LCM = 4475645460
Thus, we can understand that the LCM of 620,781,585,711 is 4475645460.
