HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 627, 385 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 627, 385 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, 385 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, 385 is 11.
HCF(627, 385) = 11
HCF of 627, 385 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, 385 is 11.
Highest Common Factor of 627,385 is 11
Step 1: Since 627 > 385, we apply the division lemma to 627 and 385, to get
627 = 385 x 1 + 242
Step 2: Since the reminder 385 ≠ 0, we apply division lemma to 242 and 385, to get
385 = 242 x 1 + 143
Step 3: We consider the new divisor 242 and the new remainder 143, and apply the division lemma to get
242 = 143 x 1 + 99
We consider the new divisor 143 and the new remainder 99,and apply the division lemma to get
143 = 99 x 1 + 44
We consider the new divisor 99 and the new remainder 44,and apply the division lemma to get
99 = 44 x 2 + 11
We consider the new divisor 44 and the new remainder 11,and apply the division lemma to get
44 = 11 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 627 and 385 is 11
Notice that 11 = HCF(44,11) = HCF(99,44) = HCF(143,99) = HCF(242,143) = HCF(385,242) = HCF(627,385) .
