HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 162, 764, 636 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 162, 764, 636 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 162, 764, 636 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 162, 764, 636 is 2.
HCF(162, 764, 636) = 2
HCF of 162, 764, 636 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 162, 764, 636 is 2.
Highest Common Factor of 162,764,636 is 2
Step 1: Since 764 > 162, we apply the division lemma to 764 and 162, to get
764 = 162 x 4 + 116
Step 2: Since the reminder 162 ≠ 0, we apply division lemma to 116 and 162, to get
162 = 116 x 1 + 46
Step 3: We consider the new divisor 116 and the new remainder 46, and apply the division lemma to get
116 = 46 x 2 + 24
We consider the new divisor 46 and the new remainder 24,and apply the division lemma to get
46 = 24 x 1 + 22
We consider the new divisor 24 and the new remainder 22,and apply the division lemma to get
24 = 22 x 1 + 2
We consider the new divisor 22 and the new remainder 2,and apply the division lemma to get
22 = 2 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 162 and 764 is 2
Notice that 2 = HCF(22,2) = HCF(24,22) = HCF(46,24) = HCF(116,46) = HCF(162,116) = HCF(764,162) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 636 > 2, we apply the division lemma to 636 and 2, to get
636 = 2 x 318 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 636 is 2
Notice that 2 = HCF(636,2) .
