HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 505, 427 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 505, 427 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 505, 427 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 505, 427 is 1.
HCF(505, 427) = 1
HCF of 505, 427 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 505, 427 is 1.
Highest Common Factor of 505,427 is 1
Step 1: Since 505 > 427, we apply the division lemma to 505 and 427, to get
505 = 427 x 1 + 78
Step 2: Since the reminder 427 ≠ 0, we apply division lemma to 78 and 427, to get
427 = 78 x 5 + 37
Step 3: We consider the new divisor 78 and the new remainder 37, and apply the division lemma to get
78 = 37 x 2 + 4
We consider the new divisor 37 and the new remainder 4,and apply the division lemma to get
37 = 4 x 9 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma 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 505 and 427 is 1
Notice that 1 = HCF(4,1) = HCF(37,4) = HCF(78,37) = HCF(427,78) = HCF(505,427) .
