HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 782, 947, 875 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 782, 947, 875 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 782, 947, 875 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 782, 947, 875 is 1.
HCF(782, 947, 875) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 782, 947, 875 is 1.
Step 1: Since 947 > 782, we apply the division lemma to 947 and 782, to get
947 = 782 x 1 + 165
Step 2: Since the reminder 782 ≠ 0, we apply division lemma to 165 and 782, to get
782 = 165 x 4 + 122
Step 3: We consider the new divisor 165 and the new remainder 122, and apply the division lemma to get
165 = 122 x 1 + 43
We consider the new divisor 122 and the new remainder 43,and apply the division lemma to get
122 = 43 x 2 + 36
We consider the new divisor 43 and the new remainder 36,and apply the division lemma to get
43 = 36 x 1 + 7
We consider the new divisor 36 and the new remainder 7,and apply the division lemma to get
36 = 7 x 5 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 782 and 947 is 1
Notice that 1 = HCF(7,1) = HCF(36,7) = HCF(43,36) = HCF(122,43) = HCF(165,122) = HCF(782,165) = HCF(947,782) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 875 > 1, we apply the division lemma to 875 and 1, to get
875 = 1 x 875 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 875 is 1
Notice that 1 = HCF(875,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 782, 947, 875?
Answer: HCF of 782, 947, 875 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 782, 947, 875 using Euclid's Algorithm?
Answer: For arbitrary numbers 782, 947, 875 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
