HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 91, 81, 106, 969 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 91, 81, 106, 969 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 91, 81, 106, 969 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 91, 81, 106, 969 is 1.
HCF(91, 81, 106, 969) = 1
HCF of 91, 81, 106, 969 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 91, 81, 106, 969 is 1.
Highest Common Factor of 91,81,106,969 is 1
Step 1: Since 91 > 81, we apply the division lemma to 91 and 81, to get
91 = 81 x 1 + 10
Step 2: Since the reminder 81 ≠ 0, we apply division lemma to 10 and 81, to get
81 = 10 x 8 + 1
Step 3: We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 91 and 81 is 1
Notice that 1 = HCF(10,1) = HCF(81,10) = HCF(91,81) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 106 > 1, we apply the division lemma to 106 and 1, to get
106 = 1 x 106 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 106 is 1
Notice that 1 = HCF(106,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 969 > 1, we apply the division lemma to 969 and 1, to get
969 = 1 x 969 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 969 is 1
Notice that 1 = HCF(969,1) .
