HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 676, 406, 909 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 676, 406, 909 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 676, 406, 909 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 676, 406, 909 is 1.
HCF(676, 406, 909) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 676, 406, 909 is 1.
Step 1: Since 676 > 406, we apply the division lemma to 676 and 406, to get
676 = 406 x 1 + 270
Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 270 and 406, to get
406 = 270 x 1 + 136
Step 3: We consider the new divisor 270 and the new remainder 136, and apply the division lemma to get
270 = 136 x 1 + 134
We consider the new divisor 136 and the new remainder 134,and apply the division lemma to get
136 = 134 x 1 + 2
We consider the new divisor 134 and the new remainder 2,and apply the division lemma to get
134 = 2 x 67 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 676 and 406 is 2
Notice that 2 = HCF(134,2) = HCF(136,134) = HCF(270,136) = HCF(406,270) = HCF(676,406) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 909 > 2, we apply the division lemma to 909 and 2, to get
909 = 2 x 454 + 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 909 is 1
Notice that 1 = HCF(2,1) = HCF(909,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 676, 406, 909?
Answer: HCF of 676, 406, 909 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 676, 406, 909 using Euclid's Algorithm?
Answer: For arbitrary numbers 676, 406, 909 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
