HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 427, 761, 571 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 427, 761, 571 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 427, 761, 571 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 427, 761, 571 is 1.
HCF(427, 761, 571) = 1
HCF of 427, 761, 571 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 427, 761, 571 is 1.
Highest Common Factor of 427,761,571 is 1
Step 1: Since 761 > 427, we apply the division lemma to 761 and 427, to get
761 = 427 x 1 + 334
Step 2: Since the reminder 427 ≠ 0, we apply division lemma to 334 and 427, to get
427 = 334 x 1 + 93
Step 3: We consider the new divisor 334 and the new remainder 93, and apply the division lemma to get
334 = 93 x 3 + 55
We consider the new divisor 93 and the new remainder 55,and apply the division lemma to get
93 = 55 x 1 + 38
We consider the new divisor 55 and the new remainder 38,and apply the division lemma to get
55 = 38 x 1 + 17
We consider the new divisor 38 and the new remainder 17,and apply the division lemma to get
38 = 17 x 2 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 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 427 and 761 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(38,17) = HCF(55,38) = HCF(93,55) = HCF(334,93) = HCF(427,334) = HCF(761,427) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 571 > 1, we apply the division lemma to 571 and 1, to get
571 = 1 x 571 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 571 is 1
Notice that 1 = HCF(571,1) .
