HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 69, 30, 27, 236 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 69, 30, 27, 236 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 69, 30, 27, 236 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 69, 30, 27, 236 is 1.
HCF(69, 30, 27, 236) = 1
HCF of 69, 30, 27, 236 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 69, 30, 27, 236 is 1.
Highest Common Factor of 69,30,27,236 is 1
Step 1: Since 69 > 30, we apply the division lemma to 69 and 30, to get
69 = 30 x 2 + 9
Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 9 and 30, to get
30 = 9 x 3 + 3
Step 3: We consider the new divisor 9 and the new remainder 3, and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 69 and 30 is 3
Notice that 3 = HCF(9,3) = HCF(30,9) = HCF(69,30) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 27 > 3, we apply the division lemma to 27 and 3, to get
27 = 3 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 27 is 3
Notice that 3 = HCF(27,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 236 > 3, we apply the division lemma to 236 and 3, to get
236 = 3 x 78 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 236 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(236,3) .
