HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 677, 21, 268, 995 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 677, 21, 268, 995 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 677, 21, 268, 995 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 677, 21, 268, 995 is 1.
HCF(677, 21, 268, 995) = 1
HCF of 677, 21, 268, 995 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 677, 21, 268, 995 is 1.
Highest Common Factor of 677,21,268,995 is 1
Step 1: Since 677 > 21, we apply the division lemma to 677 and 21, to get
677 = 21 x 32 + 5
Step 2: Since the reminder 21 ≠ 0, we apply division lemma to 5 and 21, to get
21 = 5 x 4 + 1
Step 3: We consider the new divisor 5 and the new remainder 1, and apply the division lemma 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 677 and 21 is 1
Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(677,21) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 268 > 1, we apply the division lemma to 268 and 1, to get
268 = 1 x 268 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 268 is 1
Notice that 1 = HCF(268,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 995 > 1, we apply the division lemma to 995 and 1, to get
995 = 1 x 995 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 995 is 1
Notice that 1 = HCF(995,1) .
