HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 422, 938 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 422, 938 is 2 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 422, 938 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 422, 938 is 2.
HCF(422, 938) = 2
HCF of 422, 938 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 422, 938 is 2.
Highest Common Factor of 422,938 is 2
Step 1: Since 938 > 422, we apply the division lemma to 938 and 422, to get
938 = 422 x 2 + 94
Step 2: Since the reminder 422 ≠ 0, we apply division lemma to 94 and 422, to get
422 = 94 x 4 + 46
Step 3: We consider the new divisor 94 and the new remainder 46, and apply the division lemma to get
94 = 46 x 2 + 2
We consider the new divisor 46 and the new remainder 2, and apply the division lemma to get
46 = 2 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 422 and 938 is 2
Notice that 2 = HCF(46,2) = HCF(94,46) = HCF(422,94) = HCF(938,422) .
