HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 272, 731, 667, 660 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 272, 731, 667, 660 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, 731, 667, 660 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, 731, 667, 660 is 1.
HCF(272, 731, 667, 660) = 1
HCF of 272, 731, 667, 660 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, 731, 667, 660 is 1.
Highest Common Factor of 272,731,667,660 is 1
Step 1: Since 731 > 272, we apply the division lemma to 731 and 272, to get
731 = 272 x 2 + 187
Step 2: Since the reminder 272 ≠ 0, we apply division lemma to 187 and 272, to get
272 = 187 x 1 + 85
Step 3: We consider the new divisor 187 and the new remainder 85, and apply the division lemma to get
187 = 85 x 2 + 17
We consider the new divisor 85 and the new remainder 17, and apply the division lemma to get
85 = 17 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 272 and 731 is 17
Notice that 17 = HCF(85,17) = HCF(187,85) = HCF(272,187) = HCF(731,272) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 667 > 17, we apply the division lemma to 667 and 17, to get
667 = 17 x 39 + 4
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 4 and 17, to get
17 = 4 x 4 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma 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 17 and 667 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(667,17) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 660 > 1, we apply the division lemma to 660 and 1, to get
660 = 1 x 660 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 660 is 1
Notice that 1 = HCF(660,1) .
