HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 477, 771, 454 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 477, 771, 454 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 477, 771, 454 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 477, 771, 454 is 1.
HCF(477, 771, 454) = 1
HCF of 477, 771, 454 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 477, 771, 454 is 1.
Highest Common Factor of 477,771,454 is 1
Step 1: Since 771 > 477, we apply the division lemma to 771 and 477, to get
771 = 477 x 1 + 294
Step 2: Since the reminder 477 ≠ 0, we apply division lemma to 294 and 477, to get
477 = 294 x 1 + 183
Step 3: We consider the new divisor 294 and the new remainder 183, and apply the division lemma to get
294 = 183 x 1 + 111
We consider the new divisor 183 and the new remainder 111,and apply the division lemma to get
183 = 111 x 1 + 72
We consider the new divisor 111 and the new remainder 72,and apply the division lemma to get
111 = 72 x 1 + 39
We consider the new divisor 72 and the new remainder 39,and apply the division lemma to get
72 = 39 x 1 + 33
We consider the new divisor 39 and the new remainder 33,and apply the division lemma to get
39 = 33 x 1 + 6
We consider the new divisor 33 and the new remainder 6,and apply the division lemma to get
33 = 6 x 5 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 477 and 771 is 3
Notice that 3 = HCF(6,3) = HCF(33,6) = HCF(39,33) = HCF(72,39) = HCF(111,72) = HCF(183,111) = HCF(294,183) = HCF(477,294) = HCF(771,477) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 454 > 3, we apply the division lemma to 454 and 3, to get
454 = 3 x 151 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 454 is 1
Notice that 1 = HCF(3,1) = HCF(454,3) .
