HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 478, 180 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 478, 180 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, 180 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, 180 is 2.
HCF(478, 180) = 2
HCF of 478, 180 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, 180 is 2.
Highest Common Factor of 478,180 is 2
Step 1: Since 478 > 180, we apply the division lemma to 478 and 180, to get
478 = 180 x 2 + 118
Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 118 and 180, to get
180 = 118 x 1 + 62
Step 3: We consider the new divisor 118 and the new remainder 62, and apply the division lemma to get
118 = 62 x 1 + 56
We consider the new divisor 62 and the new remainder 56,and apply the division lemma to get
62 = 56 x 1 + 6
We consider the new divisor 56 and the new remainder 6,and apply the division lemma to get
56 = 6 x 9 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 478 and 180 is 2
Notice that 2 = HCF(6,2) = HCF(56,6) = HCF(62,56) = HCF(118,62) = HCF(180,118) = HCF(478,180) .
