HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 965, 772, 644 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 965, 772, 644 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 965, 772, 644 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 965, 772, 644 is 1.
HCF(965, 772, 644) = 1
HCF of 965, 772, 644 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 965, 772, 644 is 1.
Highest Common Factor of 965,772,644 is 1
Step 1: Since 965 > 772, we apply the division lemma to 965 and 772, to get
965 = 772 x 1 + 193
Step 2: Since the reminder 772 ≠ 0, we apply division lemma to 193 and 772, to get
772 = 193 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 193, the HCF of 965 and 772 is 193
Notice that 193 = HCF(772,193) = HCF(965,772) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 644 > 193, we apply the division lemma to 644 and 193, to get
644 = 193 x 3 + 65
Step 2: Since the reminder 193 ≠ 0, we apply division lemma to 65 and 193, to get
193 = 65 x 2 + 63
Step 3: We consider the new divisor 65 and the new remainder 63, and apply the division lemma to get
65 = 63 x 1 + 2
We consider the new divisor 63 and the new remainder 2,and apply the division lemma to get
63 = 2 x 31 + 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 193 and 644 is 1
Notice that 1 = HCF(2,1) = HCF(63,2) = HCF(65,63) = HCF(193,65) = HCF(644,193) .
