Given numbers are 980,978,551,790,724
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,978,551,790,724 is 3775654095780.
Find LCM of 980,978,551,790,724 with Prime Factorization
| 2 | 980, 978, 551, 790, 724 |
| 2 | 490, 489, 551, 395, 362 |
| 5 | 245, 489, 551, 395, 181 |
| 49, 489, 551, 79, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 49 x 489 x 551 x 79 x 181 = 3775654095780
Therefore, the lowest common multiple of 980,978,551,790,724 is 3775654095780.
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.
980 x 978 x 551 x 790 x 724 = 302052327662400
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
978 : 1, 2, 3, 6, 163, 326, 489, 978
551 : 1, 19, 29, 551
790 : 1, 2, 5, 10, 79, 158, 395, 790
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,978,551,790,724, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
978:2x 3x 163
551:19x 29
790:2x 5x 79
724:2x 2x 181
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 5 = 80
Therefore, the value for common factors is 80.
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 = 302052327662400/(1x80)
LCM = 302052327662400/80
LCM = 3775654095780
Thus, we can understand that the LCM of 980,978,551,790,724 is 3775654095780.
