HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 761, 656, 221, 571 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 761, 656, 221, 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 761, 656, 221, 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 761, 656, 221, 571 is 1.
HCF(761, 656, 221, 571) = 1
HCF of 761, 656, 221, 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 761, 656, 221, 571 is 1.
Highest Common Factor of 761,656,221,571 is 1
Step 1: Since 761 > 656, we apply the division lemma to 761 and 656, to get
761 = 656 x 1 + 105
Step 2: Since the reminder 656 ≠ 0, we apply division lemma to 105 and 656, to get
656 = 105 x 6 + 26
Step 3: We consider the new divisor 105 and the new remainder 26, and apply the division lemma to get
105 = 26 x 4 + 1
We consider the new divisor 26 and the new remainder 1, and apply the division lemma to get
26 = 1 x 26 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 761 and 656 is 1
Notice that 1 = HCF(26,1) = HCF(105,26) = HCF(656,105) = HCF(761,656) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 221 > 1, we apply the division lemma to 221 and 1, to get
221 = 1 x 221 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 221 is 1
Notice that 1 = HCF(221,1) .
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) .
