HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 602, 385 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 602, 385 is 7 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 602, 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 602, 385 is 7.
HCF(602, 385) = 7
HCF of 602, 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 602, 385 is 7.
Highest Common Factor of 602,385 is 7
Step 1: Since 602 > 385, we apply the division lemma to 602 and 385, to get
602 = 385 x 1 + 217
Step 2: Since the reminder 385 ≠ 0, we apply division lemma to 217 and 385, to get
385 = 217 x 1 + 168
Step 3: We consider the new divisor 217 and the new remainder 168, and apply the division lemma to get
217 = 168 x 1 + 49
We consider the new divisor 168 and the new remainder 49,and apply the division lemma to get
168 = 49 x 3 + 21
We consider the new divisor 49 and the new remainder 21,and apply the division lemma to get
49 = 21 x 2 + 7
We consider the new divisor 21 and the new remainder 7,and apply the division lemma to get
21 = 7 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 602 and 385 is 7
Notice that 7 = HCF(21,7) = HCF(49,21) = HCF(168,49) = HCF(217,168) = HCF(385,217) = HCF(602,385) .
