HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 407, 242 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 407, 242 is 11 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 407, 242 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 407, 242 is 11.
HCF(407, 242) = 11
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 407, 242 is 11.
Step 1: Since 407 > 242, we apply the division lemma to 407 and 242, to get
407 = 242 x 1 + 165
Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 165 and 242, to get
242 = 165 x 1 + 77
Step 3: We consider the new divisor 165 and the new remainder 77, and apply the division lemma to get
165 = 77 x 2 + 11
We consider the new divisor 77 and the new remainder 11, and apply the division lemma to get
77 = 11 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 407 and 242 is 11
Notice that 11 = HCF(77,11) = HCF(165,77) = HCF(242,165) = HCF(407,242) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 407, 242?
Answer: HCF of 407, 242 is 11 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 407, 242 using Euclid's Algorithm?
Answer: For arbitrary numbers 407, 242 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
