HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 986, 789, 477 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 986, 789, 477 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 986, 789, 477 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 986, 789, 477 is 1.
HCF(986, 789, 477) = 1
HCF of 986, 789, 477 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 986, 789, 477 is 1.
Highest Common Factor of 986,789,477 is 1
Step 1: Since 986 > 789, we apply the division lemma to 986 and 789, to get
986 = 789 x 1 + 197
Step 2: Since the reminder 789 ≠ 0, we apply division lemma to 197 and 789, to get
789 = 197 x 4 + 1
Step 3: We consider the new divisor 197 and the new remainder 1, and apply the division lemma to get
197 = 1 x 197 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 986 and 789 is 1
Notice that 1 = HCF(197,1) = HCF(789,197) = HCF(986,789) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 477 > 1, we apply the division lemma to 477 and 1, to get
477 = 1 x 477 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 477 is 1
Notice that 1 = HCF(477,1) .
