HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 52, 78, 10, 909 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 52, 78, 10, 909 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 52, 78, 10, 909 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 52, 78, 10, 909 is 1.
HCF(52, 78, 10, 909) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 52, 78, 10, 909 is 1.
Step 1: Since 78 > 52, we apply the division lemma to 78 and 52, to get
78 = 52 x 1 + 26
Step 2: Since the reminder 52 ≠ 0, we apply division lemma to 26 and 52, to get
52 = 26 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 26, the HCF of 52 and 78 is 26
Notice that 26 = HCF(52,26) = HCF(78,52) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 26 > 10, we apply the division lemma to 26 and 10, to get
26 = 10 x 2 + 6
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 6 and 10, to get
10 = 6 x 1 + 4
Step 3: We consider the new divisor 6 and the new remainder 4, and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 26 and 10 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(26,10) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 909 > 2, we apply the division lemma to 909 and 2, to get
909 = 2 x 454 + 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 909 is 1
Notice that 1 = HCF(2,1) = HCF(909,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 52, 78, 10, 909?
Answer: HCF of 52, 78, 10, 909 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 52, 78, 10, 909 using Euclid's Algorithm?
Answer: For arbitrary numbers 52, 78, 10, 909 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
