HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 693, 867, 978 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 693, 867, 978 is 3 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 693, 867, 978 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 693, 867, 978 is 3.
HCF(693, 867, 978) = 3
HCF of 693, 867, 978 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 693, 867, 978 is 3.
Highest Common Factor of 693,867,978 is 3
Step 1: Since 867 > 693, we apply the division lemma to 867 and 693, to get
867 = 693 x 1 + 174
Step 2: Since the reminder 693 ≠ 0, we apply division lemma to 174 and 693, to get
693 = 174 x 3 + 171
Step 3: We consider the new divisor 174 and the new remainder 171, and apply the division lemma to get
174 = 171 x 1 + 3
We consider the new divisor 171 and the new remainder 3, and apply the division lemma to get
171 = 3 x 57 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 693 and 867 is 3
Notice that 3 = HCF(171,3) = HCF(174,171) = HCF(693,174) = HCF(867,693) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 978 > 3, we apply the division lemma to 978 and 3, to get
978 = 3 x 326 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 978 is 3
Notice that 3 = HCF(978,3) .
