HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 530, 646, 762 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 530, 646, 762 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, 646, 762 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, 646, 762 is 2.
HCF(530, 646, 762) = 2
HCF of 530, 646, 762 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, 646, 762 is 2.
Highest Common Factor of 530,646,762 is 2
Step 1: Since 646 > 530, we apply the division lemma to 646 and 530, to get
646 = 530 x 1 + 116
Step 2: Since the reminder 530 ≠ 0, we apply division lemma to 116 and 530, to get
530 = 116 x 4 + 66
Step 3: We consider the new divisor 116 and the new remainder 66, and apply the division lemma to get
116 = 66 x 1 + 50
We consider the new divisor 66 and the new remainder 50,and apply the division lemma to get
66 = 50 x 1 + 16
We consider the new divisor 50 and the new remainder 16,and apply the division lemma to get
50 = 16 x 3 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 530 and 646 is 2
Notice that 2 = HCF(16,2) = HCF(50,16) = HCF(66,50) = HCF(116,66) = HCF(530,116) = HCF(646,530) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 762 > 2, we apply the division lemma to 762 and 2, to get
762 = 2 x 381 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 762 is 2
Notice that 2 = HCF(762,2) .
