HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 981, 388, 104 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 981, 388, 104 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 981, 388, 104 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 981, 388, 104 is 1.
HCF(981, 388, 104) = 1
HCF of 981, 388, 104 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 981, 388, 104 is 1.
Highest Common Factor of 981,388,104 is 1
Step 1: Since 981 > 388, we apply the division lemma to 981 and 388, to get
981 = 388 x 2 + 205
Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 205 and 388, to get
388 = 205 x 1 + 183
Step 3: We consider the new divisor 205 and the new remainder 183, and apply the division lemma to get
205 = 183 x 1 + 22
We consider the new divisor 183 and the new remainder 22,and apply the division lemma to get
183 = 22 x 8 + 7
We consider the new divisor 22 and the new remainder 7,and apply the division lemma to get
22 = 7 x 3 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 981 and 388 is 1
Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(183,22) = HCF(205,183) = HCF(388,205) = HCF(981,388) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 104 > 1, we apply the division lemma to 104 and 1, to get
104 = 1 x 104 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 104 is 1
Notice that 1 = HCF(104,1) .
