HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 540, 378, 882 i.e. 18 the largest integer that leaves a remainder zero for all numbers.
HCF of 540, 378, 882 is 18 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 540, 378, 882 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 540, 378, 882 is 18.
HCF(540, 378, 882) = 18
HCF of 540, 378, 882 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 540, 378, 882 is 18.
Highest Common Factor of 540,378,882 is 18
Step 1: Since 540 > 378, we apply the division lemma to 540 and 378, to get
540 = 378 x 1 + 162
Step 2: Since the reminder 378 ≠ 0, we apply division lemma to 162 and 378, to get
378 = 162 x 2 + 54
Step 3: We consider the new divisor 162 and the new remainder 54, and apply the division lemma to get
162 = 54 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 54, the HCF of 540 and 378 is 54
Notice that 54 = HCF(162,54) = HCF(378,162) = HCF(540,378) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 882 > 54, we apply the division lemma to 882 and 54, to get
882 = 54 x 16 + 18
Step 2: Since the reminder 54 ≠ 0, we apply division lemma to 18 and 54, to get
54 = 18 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 54 and 882 is 18
Notice that 18 = HCF(54,18) = HCF(882,54) .
