HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 76, 77, 966, 987 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 76, 77, 966, 987 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 76, 77, 966, 987 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 76, 77, 966, 987 is 1.
HCF(76, 77, 966, 987) = 1
HCF of 76, 77, 966, 987 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 76, 77, 966, 987 is 1.
Highest Common Factor of 76,77,966,987 is 1
Step 1: Since 77 > 76, we apply the division lemma to 77 and 76, to get
77 = 76 x 1 + 1
Step 2: Since the reminder 76 ≠ 0, we apply division lemma to 1 and 76, to get
76 = 1 x 76 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 76 and 77 is 1
Notice that 1 = HCF(76,1) = HCF(77,76) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 966 > 1, we apply the division lemma to 966 and 1, to get
966 = 1 x 966 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 966 is 1
Notice that 1 = HCF(966,1) .
