HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 656, 204, 162 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 656, 204, 162 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 656, 204, 162 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 656, 204, 162 is 2.
HCF(656, 204, 162) = 2
HCF of 656, 204, 162 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 656, 204, 162 is 2.
Highest Common Factor of 656,204,162 is 2
Step 1: Since 656 > 204, we apply the division lemma to 656 and 204, to get
656 = 204 x 3 + 44
Step 2: Since the reminder 204 ≠ 0, we apply division lemma to 44 and 204, to get
204 = 44 x 4 + 28
Step 3: We consider the new divisor 44 and the new remainder 28, and apply the division lemma to get
44 = 28 x 1 + 16
We consider the new divisor 28 and the new remainder 16,and apply the division lemma to get
28 = 16 x 1 + 12
We consider the new divisor 16 and the new remainder 12,and apply the division lemma to get
16 = 12 x 1 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 656 and 204 is 4
Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(28,16) = HCF(44,28) = HCF(204,44) = HCF(656,204) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 162 > 4, we apply the division lemma to 162 and 4, to get
162 = 4 x 40 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, 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 4 and 162 is 2
Notice that 2 = HCF(4,2) = HCF(162,4) .
