HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 95, 19, 20 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 95, 19, 20 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 95, 19, 20 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 95, 19, 20 is 1.
HCF(95, 19, 20) = 1
HCF of 95, 19, 20 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 95, 19, 20 is 1.
Highest Common Factor of 95,19,20 is 1
Step 1: Since 95 > 19, we apply the division lemma to 95 and 19, to get
95 = 19 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 95 and 19 is 19
Notice that 19 = HCF(95,19) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 20 > 19, we apply the division lemma to 20 and 19, to get
20 = 19 x 1 + 1
Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 1 and 19, to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 19 and 20 is 1
Notice that 1 = HCF(19,1) = HCF(20,19) .
