HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 324, 405, 565 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 324, 405, 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 324, 405, 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 324, 405, 565 is 1.
HCF(324, 405, 565) = 1
HCF of 324, 405, 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 324, 405, 565 is 1.
Highest Common Factor of 324,405,565 is 1
Step 1: Since 405 > 324, we apply the division lemma to 405 and 324, to get
405 = 324 x 1 + 81
Step 2: Since the reminder 324 ≠ 0, we apply division lemma to 81 and 324, to get
324 = 81 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 81, the HCF of 324 and 405 is 81
Notice that 81 = HCF(324,81) = HCF(405,324) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 565 > 81, we apply the division lemma to 565 and 81, to get
565 = 81 x 6 + 79
Step 2: Since the reminder 81 ≠ 0, we apply division lemma to 79 and 81, to get
81 = 79 x 1 + 2
Step 3: 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 81 and 565 is 1
Notice that 1 = HCF(2,1) = HCF(79,2) = HCF(81,79) = HCF(565,81) .
