HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 15, 80, 66, 696 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 15, 80, 66, 696 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 15, 80, 66, 696 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 15, 80, 66, 696 is 1.
HCF(15, 80, 66, 696) = 1
HCF of 15, 80, 66, 696 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 15, 80, 66, 696 is 1.
Highest Common Factor of 15,80,66,696 is 1
Step 1: Since 80 > 15, we apply the division lemma to 80 and 15, to get
80 = 15 x 5 + 5
Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 5 and 15, to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 15 and 80 is 5
Notice that 5 = HCF(15,5) = HCF(80,15) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 66 > 5, we apply the division lemma to 66 and 5, to get
66 = 5 x 13 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 66 is 1
Notice that 1 = HCF(5,1) = HCF(66,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 696 > 1, we apply the division lemma to 696 and 1, to get
696 = 1 x 696 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 696 is 1
Notice that 1 = HCF(696,1) .
