HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 123, 328 i.e. 41 the largest integer that leaves a remainder zero for all numbers.
HCF of 123, 328 is 41 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 123, 328 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 123, 328 is 41.
HCF(123, 328) = 41
HCF of 123, 328 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 123, 328 is 41.
Highest Common Factor of 123,328 is 41
Step 1: Since 328 > 123, we apply the division lemma to 328 and 123, to get
328 = 123 x 2 + 82
Step 2: Since the reminder 123 ≠ 0, we apply division lemma to 82 and 123, to get
123 = 82 x 1 + 41
Step 3: We consider the new divisor 82 and the new remainder 41, and apply the division lemma to get
82 = 41 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 41, the HCF of 123 and 328 is 41
Notice that 41 = HCF(82,41) = HCF(123,82) = HCF(328,123) .
