HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 609, 907, 78, 403 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 609, 907, 78, 403 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 609, 907, 78, 403 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 609, 907, 78, 403 is 1.
HCF(609, 907, 78, 403) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 609, 907, 78, 403 is 1.
Step 1: Since 907 > 609, we apply the division lemma to 907 and 609, to get
907 = 609 x 1 + 298
Step 2: Since the reminder 609 ≠ 0, we apply division lemma to 298 and 609, to get
609 = 298 x 2 + 13
Step 3: We consider the new divisor 298 and the new remainder 13, and apply the division lemma to get
298 = 13 x 22 + 12
We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get
13 = 12 x 1 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 609 and 907 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(298,13) = HCF(609,298) = HCF(907,609) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 78 > 1, we apply the division lemma to 78 and 1, to get
78 = 1 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 78 is 1
Notice that 1 = HCF(78,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 403 > 1, we apply the division lemma to 403 and 1, to get
403 = 1 x 403 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 403 is 1
Notice that 1 = HCF(403,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 609, 907, 78, 403?
Answer: HCF of 609, 907, 78, 403 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 609, 907, 78, 403 using Euclid's Algorithm?
Answer: For arbitrary numbers 609, 907, 78, 403 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
