HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 967, 174 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 820, 967, 174 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 820, 967, 174 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 820, 967, 174 is 1.
HCF(820, 967, 174) = 1
HCF of 820, 967, 174 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 820, 967, 174 is 1.
Highest Common Factor of 820,967,174 is 1
Step 1: Since 967 > 820, we apply the division lemma to 967 and 820, to get
967 = 820 x 1 + 147
Step 2: Since the reminder 820 ≠ 0, we apply division lemma to 147 and 820, to get
820 = 147 x 5 + 85
Step 3: We consider the new divisor 147 and the new remainder 85, and apply the division lemma to get
147 = 85 x 1 + 62
We consider the new divisor 85 and the new remainder 62,and apply the division lemma to get
85 = 62 x 1 + 23
We consider the new divisor 62 and the new remainder 23,and apply the division lemma to get
62 = 23 x 2 + 16
We consider the new divisor 23 and the new remainder 16,and apply the division lemma to get
23 = 16 x 1 + 7
We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get
16 = 7 x 2 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 820 and 967 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(23,16) = HCF(62,23) = HCF(85,62) = HCF(147,85) = HCF(820,147) = HCF(967,820) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 174 > 1, we apply the division lemma to 174 and 1, to get
174 = 1 x 174 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 174 is 1
Notice that 1 = HCF(174,1) .
