HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 529, 195, 154 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 529, 195, 154 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 529, 195, 154 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 529, 195, 154 is 1.
HCF(529, 195, 154) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 529, 195, 154 is 1.
Step 1: Since 529 > 195, we apply the division lemma to 529 and 195, to get
529 = 195 x 2 + 139
Step 2: Since the reminder 195 ≠ 0, we apply division lemma to 139 and 195, to get
195 = 139 x 1 + 56
Step 3: We consider the new divisor 139 and the new remainder 56, and apply the division lemma to get
139 = 56 x 2 + 27
We consider the new divisor 56 and the new remainder 27,and apply the division lemma to get
56 = 27 x 2 + 2
We consider the new divisor 27 and the new remainder 2,and apply the division lemma to get
27 = 2 x 13 + 1
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 529 and 195 is 1
Notice that 1 = HCF(2,1) = HCF(27,2) = HCF(56,27) = HCF(139,56) = HCF(195,139) = HCF(529,195) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 154 > 1, we apply the division lemma to 154 and 1, to get
154 = 1 x 154 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 154 is 1
Notice that 1 = HCF(154,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 529, 195, 154?
Answer: HCF of 529, 195, 154 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 529, 195, 154 using Euclid's Algorithm?
Answer: For arbitrary numbers 529, 195, 154 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
