HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 216, 945, 276 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 216, 945, 276 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 216, 945, 276 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 216, 945, 276 is 3.
HCF(216, 945, 276) = 3
HCF of 216, 945, 276 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 216, 945, 276 is 3.
Highest Common Factor of 216,945,276 is 3
Step 1: Since 945 > 216, we apply the division lemma to 945 and 216, to get
945 = 216 x 4 + 81
Step 2: Since the reminder 216 ≠ 0, we apply division lemma to 81 and 216, to get
216 = 81 x 2 + 54
Step 3: We consider the new divisor 81 and the new remainder 54, and apply the division lemma to get
81 = 54 x 1 + 27
We consider the new divisor 54 and the new remainder 27, and apply the division lemma to get
54 = 27 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 216 and 945 is 27
Notice that 27 = HCF(54,27) = HCF(81,54) = HCF(216,81) = HCF(945,216) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 276 > 27, we apply the division lemma to 276 and 27, to get
276 = 27 x 10 + 6
Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 6 and 27, to get
27 = 6 x 4 + 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 27 and 276 is 3
Notice that 3 = HCF(6,3) = HCF(27,6) = HCF(276,27) .
