HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 20, 64, 96, 717 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 20, 64, 96, 717 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 20, 64, 96, 717 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 20, 64, 96, 717 is 1.
HCF(20, 64, 96, 717) = 1
HCF of 20, 64, 96, 717 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 20, 64, 96, 717 is 1.
Highest Common Factor of 20,64,96,717 is 1
Step 1: Since 64 > 20, we apply the division lemma to 64 and 20, to get
64 = 20 x 3 + 4
Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 4 and 20, to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 20 and 64 is 4
Notice that 4 = HCF(20,4) = HCF(64,20) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 96 > 4, we apply the division lemma to 96 and 4, to get
96 = 4 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 96 is 4
Notice that 4 = HCF(96,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 717 > 4, we apply the division lemma to 717 and 4, to get
717 = 4 x 179 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 717 is 1
Notice that 1 = HCF(4,1) = HCF(717,4) .
