HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 63, 111 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 63, 111 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 63, 111 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 63, 111 is 3.
HCF(63, 111) = 3
HCF of 63, 111 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 63, 111 is 3.
Highest Common Factor of 63,111 is 3
Step 1: Since 111 > 63, we apply the division lemma to 111 and 63, to get
111 = 63 x 1 + 48
Step 2: Since the reminder 63 ≠ 0, we apply division lemma to 48 and 63, to get
63 = 48 x 1 + 15
Step 3: We consider the new divisor 48 and the new remainder 15, and apply the division lemma to get
48 = 15 x 3 + 3
We consider the new divisor 15 and the new remainder 3, and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 63 and 111 is 3
Notice that 3 = HCF(15,3) = HCF(48,15) = HCF(63,48) = HCF(111,63) .
