HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 302, 480 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 302, 480 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, 480 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, 480 is 2.
HCF(302, 480) = 2
HCF of 302, 480 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, 480 is 2.
Highest Common Factor of 302,480 is 2
Step 1: Since 480 > 302, we apply the division lemma to 480 and 302, to get
480 = 302 x 1 + 178
Step 2: Since the reminder 302 ≠ 0, we apply division lemma to 178 and 302, to get
302 = 178 x 1 + 124
Step 3: We consider the new divisor 178 and the new remainder 124, and apply the division lemma to get
178 = 124 x 1 + 54
We consider the new divisor 124 and the new remainder 54,and apply the division lemma to get
124 = 54 x 2 + 16
We consider the new divisor 54 and the new remainder 16,and apply the division lemma to get
54 = 16 x 3 + 6
We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get
16 = 6 x 2 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 302 and 480 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(54,16) = HCF(124,54) = HCF(178,124) = HCF(302,178) = HCF(480,302) .
