HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 321, 642 i.e. 321 the largest integer that leaves a remainder zero for all numbers.
HCF of 321, 642 is 321 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, 642 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, 642 is 321.
HCF(321, 642) = 321
HCF of 321, 642 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, 642 is 321.
Highest Common Factor of 321,642 is 321
Step 1: Since 642 > 321, we apply the division lemma to 642 and 321, to get
642 = 321 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 321, the HCF of 321 and 642 is 321
Notice that 321 = HCF(642,321) .
