Given numbers are 749,247,988,461
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,247,988,461 is 341145532.
Find LCM of 749,247,988,461 with Prime Factorization
| 13 | 749, 247, 988, 461 |
| 19 | 749, 19, 76, 461 |
| 749, 1, 4, 461 |
Multiply the prime numbers at the bottom and the left side.
13 x 19 x 749 x 1 x 4 x 461 = 341145532
Therefore, the lowest common multiple of 749,247,988,461 is 341145532.
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.
749 x 247 x 988 x 461 = 84262946404
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.
749 : 1, 7, 107, 749
247 : 1, 13, 19, 247
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
461 : 1, 461
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,247,988,461, is 1.
Now, the common factors can be found like this.
749:7x 107
247:13x 19
988:2x 2x 13x 19
461:461
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 19 = 247
Therefore, the value for common factors is 247.
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 = 84262946404/(1x247)
LCM = 84262946404/247
LCM = 341145532
Thus, we can understand that the LCM of 749,247,988,461 is 341145532.
