HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 74, 94, 69 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 74, 94, 69 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 74, 94, 69 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 74, 94, 69 is 1.
HCF(74, 94, 69) = 1
HCF of 74, 94, 69 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 74, 94, 69 is 1.
Highest Common Factor of 74,94,69 is 1
Step 1: Since 94 > 74, we apply the division lemma to 94 and 74, to get
94 = 74 x 1 + 20
Step 2: Since the reminder 74 ≠ 0, we apply division lemma to 20 and 74, to get
74 = 20 x 3 + 14
Step 3: We consider the new divisor 20 and the new remainder 14, and apply the division lemma to get
20 = 14 x 1 + 6
We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get
14 = 6 x 2 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 74 and 94 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(20,14) = HCF(74,20) = HCF(94,74) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 69 > 2, we apply the division lemma to 69 and 2, to get
69 = 2 x 34 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 69 is 1
Notice that 1 = HCF(2,1) = HCF(69,2) .
