HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 627, 440 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 627, 440 is 11 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 627, 440 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 627, 440 is 11.
HCF(627, 440) = 11
HCF of 627, 440 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 627, 440 is 11.
Highest Common Factor of 627,440 is 11
Step 1: Since 627 > 440, we apply the division lemma to 627 and 440, to get
627 = 440 x 1 + 187
Step 2: Since the reminder 440 ≠ 0, we apply division lemma to 187 and 440, to get
440 = 187 x 2 + 66
Step 3: We consider the new divisor 187 and the new remainder 66, and apply the division lemma to get
187 = 66 x 2 + 55
We consider the new divisor 66 and the new remainder 55,and apply the division lemma to get
66 = 55 x 1 + 11
We consider the new divisor 55 and the new remainder 11,and apply the division lemma to get
55 = 11 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 627 and 440 is 11
Notice that 11 = HCF(55,11) = HCF(66,55) = HCF(187,66) = HCF(440,187) = HCF(627,440) .
