HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 758, 972, 647 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 758, 972, 647 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 758, 972, 647 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 758, 972, 647 is 1.
HCF(758, 972, 647) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 758, 972, 647 is 1.
Step 1: Since 972 > 758, we apply the division lemma to 972 and 758, to get
972 = 758 x 1 + 214
Step 2: Since the reminder 758 ≠ 0, we apply division lemma to 214 and 758, to get
758 = 214 x 3 + 116
Step 3: We consider the new divisor 214 and the new remainder 116, and apply the division lemma to get
214 = 116 x 1 + 98
We consider the new divisor 116 and the new remainder 98,and apply the division lemma to get
116 = 98 x 1 + 18
We consider the new divisor 98 and the new remainder 18,and apply the division lemma to get
98 = 18 x 5 + 8
We consider the new divisor 18 and the new remainder 8,and apply the division lemma to get
18 = 8 x 2 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 758 and 972 is 2
Notice that 2 = HCF(8,2) = HCF(18,8) = HCF(98,18) = HCF(116,98) = HCF(214,116) = HCF(758,214) = HCF(972,758) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 647 > 2, we apply the division lemma to 647 and 2, to get
647 = 2 x 323 + 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 647 is 1
Notice that 1 = HCF(2,1) = HCF(647,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 758, 972, 647?
Answer: HCF of 758, 972, 647 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 758, 972, 647 using Euclid's Algorithm?
Answer: For arbitrary numbers 758, 972, 647 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
