HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 804, 978, 627 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 804, 978, 627 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 804, 978, 627 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 804, 978, 627 is 3.
HCF(804, 978, 627) = 3
HCF of 804, 978, 627 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 804, 978, 627 is 3.
Highest Common Factor of 804,978,627 is 3
Step 1: Since 978 > 804, we apply the division lemma to 978 and 804, to get
978 = 804 x 1 + 174
Step 2: Since the reminder 804 ≠ 0, we apply division lemma to 174 and 804, to get
804 = 174 x 4 + 108
Step 3: We consider the new divisor 174 and the new remainder 108, and apply the division lemma to get
174 = 108 x 1 + 66
We consider the new divisor 108 and the new remainder 66,and apply the division lemma to get
108 = 66 x 1 + 42
We consider the new divisor 66 and the new remainder 42,and apply the division lemma to get
66 = 42 x 1 + 24
We consider the new divisor 42 and the new remainder 24,and apply the division lemma to get
42 = 24 x 1 + 18
We consider the new divisor 24 and the new remainder 18,and apply the division lemma to get
24 = 18 x 1 + 6
We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get
18 = 6 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 804 and 978 is 6
Notice that 6 = HCF(18,6) = HCF(24,18) = HCF(42,24) = HCF(66,42) = HCF(108,66) = HCF(174,108) = HCF(804,174) = HCF(978,804) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 627 > 6, we apply the division lemma to 627 and 6, to get
627 = 6 x 104 + 3
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 3 and 6, to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 6 and 627 is 3
Notice that 3 = HCF(6,3) = HCF(627,6) .
