HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 530, 656 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 530, 656 is 2 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 530, 656 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 530, 656 is 2.
HCF(530, 656) = 2
HCF of 530, 656 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 530, 656 is 2.
Highest Common Factor of 530,656 is 2
Step 1: Since 656 > 530, we apply the division lemma to 656 and 530, to get
656 = 530 x 1 + 126
Step 2: Since the reminder 530 ≠ 0, we apply division lemma to 126 and 530, to get
530 = 126 x 4 + 26
Step 3: We consider the new divisor 126 and the new remainder 26, and apply the division lemma to get
126 = 26 x 4 + 22
We consider the new divisor 26 and the new remainder 22,and apply the division lemma to get
26 = 22 x 1 + 4
We consider the new divisor 22 and the new remainder 4,and apply the division lemma to get
22 = 4 x 5 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 530 and 656 is 2
Notice that 2 = HCF(4,2) = HCF(22,4) = HCF(26,22) = HCF(126,26) = HCF(530,126) = HCF(656,530) .
