HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 781, 226 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 781, 226 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 781, 226 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 781, 226 is 1.
HCF(781, 226) = 1
HCF of 781, 226 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 781, 226 is 1.
Highest Common Factor of 781,226 is 1
Step 1: Since 781 > 226, we apply the division lemma to 781 and 226, to get
781 = 226 x 3 + 103
Step 2: Since the reminder 226 ≠ 0, we apply division lemma to 103 and 226, to get
226 = 103 x 2 + 20
Step 3: We consider the new divisor 103 and the new remainder 20, and apply the division lemma to get
103 = 20 x 5 + 3
We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get
20 = 3 x 6 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 781 and 226 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(103,20) = HCF(226,103) = HCF(781,226) .
