HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 563, 322, 565 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 563, 322, 565 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 563, 322, 565 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 563, 322, 565 is 1.
HCF(563, 322, 565) = 1
HCF of 563, 322, 565 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 563, 322, 565 is 1.
Highest Common Factor of 563,322,565 is 1
Step 1: Since 563 > 322, we apply the division lemma to 563 and 322, to get
563 = 322 x 1 + 241
Step 2: Since the reminder 322 ≠ 0, we apply division lemma to 241 and 322, to get
322 = 241 x 1 + 81
Step 3: We consider the new divisor 241 and the new remainder 81, and apply the division lemma to get
241 = 81 x 2 + 79
We consider the new divisor 81 and the new remainder 79,and apply the division lemma to get
81 = 79 x 1 + 2
We consider the new divisor 79 and the new remainder 2,and apply the division lemma to get
79 = 2 x 39 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 563 and 322 is 1
Notice that 1 = HCF(2,1) = HCF(79,2) = HCF(81,79) = HCF(241,81) = HCF(322,241) = HCF(563,322) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 565 > 1, we apply the division lemma to 565 and 1, to get
565 = 1 x 565 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 565 is 1
Notice that 1 = HCF(565,1) .
