Given numbers are 620,505,924,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,505,924,946 is 622004460.
Find LCM of 620,505,924,946 with Prime Factorization
| 2 | 620, 505, 924, 946 |
| 2 | 310, 505, 462, 473 |
| 5 | 155, 505, 231, 473 |
| 11 | 31, 101, 231, 473 |
| 31, 101, 21, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 31 x 101 x 21 x 43 = 622004460
Therefore, the lowest common multiple of 620,505,924,946 is 622004460.
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 505 x 924 x 946 = 273681962400
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
505 : 1, 5, 101, 505
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,505,924,946, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
505:5x 101
924:2x 2x 3x 7x 11
946:2x 11x 43
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 2x 5x 11 = 440
Therefore, the value for common factors is 440.
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 = 273681962400/(1x440)
LCM = 273681962400/440
LCM = 622004460
Thus, we can understand that the LCM of 620,505,924,946 is 622004460.
