HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 272, 156, 169 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 272, 156, 169 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 272, 156, 169 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 272, 156, 169 is 1.
HCF(272, 156, 169) = 1
HCF of 272, 156, 169 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 272, 156, 169 is 1.
Highest Common Factor of 272,156,169 is 1
Step 1: Since 272 > 156, we apply the division lemma to 272 and 156, to get
272 = 156 x 1 + 116
Step 2: Since the reminder 156 ≠ 0, we apply division lemma to 116 and 156, to get
156 = 116 x 1 + 40
Step 3: We consider the new divisor 116 and the new remainder 40, and apply the division lemma to get
116 = 40 x 2 + 36
We consider the new divisor 40 and the new remainder 36,and apply the division lemma to get
40 = 36 x 1 + 4
We consider the new divisor 36 and the new remainder 4,and apply the division lemma to get
36 = 4 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 272 and 156 is 4
Notice that 4 = HCF(36,4) = HCF(40,36) = HCF(116,40) = HCF(156,116) = HCF(272,156) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 169 > 4, we apply the division lemma to 169 and 4, to get
169 = 4 x 42 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, 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 4 and 169 is 1
Notice that 1 = HCF(4,1) = HCF(169,4) .
