Given numbers are 620,919,980,628,427
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,919,980,628,427 is 267382369940.
Find LCM of 620,919,980,628,427 with Prime Factorization
| 2 | 620, 919, 980, 628, 427 |
| 2 | 310, 919, 490, 314, 427 |
| 5 | 155, 919, 245, 157, 427 |
| 7 | 31, 919, 49, 157, 427 |
| 31, 919, 7, 157, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 31 x 919 x 7 x 157 x 61 = 267382369940
Therefore, the lowest common multiple of 620,919,980,628,427 is 267382369940.
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 919 x 980 x 628 x 427 = 149734127166400
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
919 : 1, 919
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
628 : 1, 2, 4, 157, 314, 628
427 : 1, 7, 61, 427
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,919,980,628,427, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
919:919
980:2x 2x 5x 7x 7
628:2x 2x 157
427:7x 61
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 2x 5x 7 = 560
Therefore, the value for common factors is 560.
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 = 149734127166400/(1x560)
LCM = 149734127166400/560
LCM = 267382369940
Thus, we can understand that the LCM of 620,919,980,628,427 is 267382369940.
