HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 757, 922, 615 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 757, 922, 615 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 757, 922, 615 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 757, 922, 615 is 1.
HCF(757, 922, 615) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 757, 922, 615 is 1.
Step 1: Since 922 > 757, we apply the division lemma to 922 and 757, to get
922 = 757 x 1 + 165
Step 2: Since the reminder 757 ≠ 0, we apply division lemma to 165 and 757, to get
757 = 165 x 4 + 97
Step 3: We consider the new divisor 165 and the new remainder 97, and apply the division lemma to get
165 = 97 x 1 + 68
We consider the new divisor 97 and the new remainder 68,and apply the division lemma to get
97 = 68 x 1 + 29
We consider the new divisor 68 and the new remainder 29,and apply the division lemma to get
68 = 29 x 2 + 10
We consider the new divisor 29 and the new remainder 10,and apply the division lemma to get
29 = 10 x 2 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 757 and 922 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(29,10) = HCF(68,29) = HCF(97,68) = HCF(165,97) = HCF(757,165) = HCF(922,757) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 615 > 1, we apply the division lemma to 615 and 1, to get
615 = 1 x 615 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 615 is 1
Notice that 1 = HCF(615,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 757, 922, 615?
Answer: HCF of 757, 922, 615 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 757, 922, 615 using Euclid's Algorithm?
Answer: For arbitrary numbers 757, 922, 615 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
