HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 21, 62, 92, 293 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 21, 62, 92, 293 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 21, 62, 92, 293 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 21, 62, 92, 293 is 1.
HCF(21, 62, 92, 293) = 1
HCF of 21, 62, 92, 293 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 21, 62, 92, 293 is 1.
Highest Common Factor of 21,62,92,293 is 1
Step 1: Since 62 > 21, we apply the division lemma to 62 and 21, to get
62 = 21 x 2 + 20
Step 2: Since the reminder 21 ≠ 0, we apply division lemma to 20 and 21, to get
21 = 20 x 1 + 1
Step 3: We consider the new divisor 20 and the new remainder 1, and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 21 and 62 is 1
Notice that 1 = HCF(20,1) = HCF(21,20) = HCF(62,21) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 92 > 1, we apply the division lemma to 92 and 1, to get
92 = 1 x 92 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 92 is 1
Notice that 1 = HCF(92,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 293 > 1, we apply the division lemma to 293 and 1, to get
293 = 1 x 293 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 293 is 1
Notice that 1 = HCF(293,1) .
