HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 917, 477, 771 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 917, 477, 771 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 917, 477, 771 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 917, 477, 771 is 1.
HCF(917, 477, 771) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 917, 477, 771 is 1.
Step 1: Since 917 > 477, we apply the division lemma to 917 and 477, to get
917 = 477 x 1 + 440
Step 2: Since the reminder 477 ≠ 0, we apply division lemma to 440 and 477, to get
477 = 440 x 1 + 37
Step 3: We consider the new divisor 440 and the new remainder 37, and apply the division lemma to get
440 = 37 x 11 + 33
We consider the new divisor 37 and the new remainder 33,and apply the division lemma to get
37 = 33 x 1 + 4
We consider the new divisor 33 and the new remainder 4,and apply the division lemma to get
33 = 4 x 8 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 917 and 477 is 1
Notice that 1 = HCF(4,1) = HCF(33,4) = HCF(37,33) = HCF(440,37) = HCF(477,440) = HCF(917,477) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 771 > 1, we apply the division lemma to 771 and 1, to get
771 = 1 x 771 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 771 is 1
Notice that 1 = HCF(771,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
