Given numbers are 397,688,847,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,688,847,986 is 114053672656.
Find LCM of 397,688,847,986 with Prime Factorization
2 | 397, 688, 847, 986 |
397, 344, 847, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 397 x 344 x 847 x 493 = 114053672656
Therefore, the lowest common multiple of 397,688,847,986 is 114053672656.
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.
397 x 688 x 847 x 986 = 228107345312
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.
397 : 1, 397
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
847 : 1, 7, 11, 77, 121, 847
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,688,847,986, is 1.
Now, the common factors can be found like this.
397:397
688:2x 2x 2x 2x 43
847:7x 11x 11
986:2x 17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 228107345312/(1x2)
LCM = 228107345312/2
LCM = 114053672656
Thus, we can understand that the LCM of 397,688,847,986 is 114053672656.
