HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 321, 639, 882 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 321, 639, 882 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 321, 639, 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 321, 639, 882 is 3.
HCF(321, 639, 882) = 3
HCF of 321, 639, 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 321, 639, 882 is 3.
Highest Common Factor of 321,639,882 is 3
Step 1: Since 639 > 321, we apply the division lemma to 639 and 321, to get
639 = 321 x 1 + 318
Step 2: Since the reminder 321 ≠ 0, we apply division lemma to 318 and 321, to get
321 = 318 x 1 + 3
Step 3: We consider the new divisor 318 and the new remainder 3, and apply the division lemma to get
318 = 3 x 106 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 321 and 639 is 3
Notice that 3 = HCF(318,3) = HCF(321,318) = HCF(639,321) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 882 > 3, we apply the division lemma to 882 and 3, to get
882 = 3 x 294 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 882 is 3
Notice that 3 = HCF(882,3) .
