HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 302, 1618 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 302, 1618 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 302, 1618 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 302, 1618 is 2.
HCF(302, 1618) = 2
HCF of 302, 1618 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 302, 1618 is 2.
Highest Common Factor of 302,1618 is 2
Step 1: Since 1618 > 302, we apply the division lemma to 1618 and 302, to get
1618 = 302 x 5 + 108
Step 2: Since the reminder 302 ≠ 0, we apply division lemma to 108 and 302, to get
302 = 108 x 2 + 86
Step 3: We consider the new divisor 108 and the new remainder 86, and apply the division lemma to get
108 = 86 x 1 + 22
We consider the new divisor 86 and the new remainder 22,and apply the division lemma to get
86 = 22 x 3 + 20
We consider the new divisor 22 and the new remainder 20,and apply the division lemma to get
22 = 20 x 1 + 2
We consider the new divisor 20 and the new remainder 2,and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 302 and 1618 is 2
Notice that 2 = HCF(20,2) = HCF(22,20) = HCF(86,22) = HCF(108,86) = HCF(302,108) = HCF(1618,302) .
