HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 478, 602 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 478, 602 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 478, 602 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 478, 602 is 2.
HCF(478, 602) = 2
HCF of 478, 602 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 478, 602 is 2.
Highest Common Factor of 478,602 is 2
Step 1: Since 602 > 478, we apply the division lemma to 602 and 478, to get
602 = 478 x 1 + 124
Step 2: Since the reminder 478 ≠ 0, we apply division lemma to 124 and 478, to get
478 = 124 x 3 + 106
Step 3: We consider the new divisor 124 and the new remainder 106, and apply the division lemma to get
124 = 106 x 1 + 18
We consider the new divisor 106 and the new remainder 18,and apply the division lemma to get
106 = 18 x 5 + 16
We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get
18 = 16 x 1 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 478 and 602 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(106,18) = HCF(124,106) = HCF(478,124) = HCF(602,478) .
