HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 76, 279, 172 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 76, 279, 172 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 76, 279, 172 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 76, 279, 172 is 1.
HCF(76, 279, 172) = 1
HCF of 76, 279, 172 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 76, 279, 172 is 1.
Highest Common Factor of 76,279,172 is 1
Step 1: Since 279 > 76, we apply the division lemma to 279 and 76, to get
279 = 76 x 3 + 51
Step 2: Since the reminder 76 ≠ 0, we apply division lemma to 51 and 76, to get
76 = 51 x 1 + 25
Step 3: We consider the new divisor 51 and the new remainder 25, and apply the division lemma to get
51 = 25 x 2 + 1
We consider the new divisor 25 and the new remainder 1, and apply the division lemma to get
25 = 1 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 76 and 279 is 1
Notice that 1 = HCF(25,1) = HCF(51,25) = HCF(76,51) = HCF(279,76) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 172 > 1, we apply the division lemma to 172 and 1, to get
172 = 1 x 172 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 172 is 1
Notice that 1 = HCF(172,1) .
