HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 567, 225, 861 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 567, 225, 861 is 3 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 567, 225, 861 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 567, 225, 861 is 3.
HCF(567, 225, 861) = 3
HCF of 567, 225, 861 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 567, 225, 861 is 3.
Highest Common Factor of 567,225,861 is 3
Step 1: Since 567 > 225, we apply the division lemma to 567 and 225, to get
567 = 225 x 2 + 117
Step 2: Since the reminder 225 ≠ 0, we apply division lemma to 117 and 225, to get
225 = 117 x 1 + 108
Step 3: We consider the new divisor 117 and the new remainder 108, and apply the division lemma to get
117 = 108 x 1 + 9
We consider the new divisor 108 and the new remainder 9, and apply the division lemma to get
108 = 9 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 567 and 225 is 9
Notice that 9 = HCF(108,9) = HCF(117,108) = HCF(225,117) = HCF(567,225) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 861 > 9, we apply the division lemma to 861 and 9, to get
861 = 9 x 95 + 6
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 6 and 9, to get
9 = 6 x 1 + 3
Step 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 9 and 861 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(861,9) .
