HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 272, 220, 139 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 272, 220, 139 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, 220, 139 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, 220, 139 is 1.
HCF(272, 220, 139) = 1
HCF of 272, 220, 139 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, 220, 139 is 1.
Highest Common Factor of 272,220,139 is 1
Step 1: Since 272 > 220, we apply the division lemma to 272 and 220, to get
272 = 220 x 1 + 52
Step 2: Since the reminder 220 ≠ 0, we apply division lemma to 52 and 220, to get
220 = 52 x 4 + 12
Step 3: We consider the new divisor 52 and the new remainder 12, and apply the division lemma to get
52 = 12 x 4 + 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 272 and 220 is 4
Notice that 4 = HCF(12,4) = HCF(52,12) = HCF(220,52) = HCF(272,220) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 139 > 4, we apply the division lemma to 139 and 4, to get
139 = 4 x 34 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 139 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(139,4) .
