HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 478, 418, 421, 62 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 478, 418, 421, 62 is 1 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, 418, 421, 62 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, 418, 421, 62 is 1.
HCF(478, 418, 421, 62) = 1
HCF of 478, 418, 421, 62 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, 418, 421, 62 is 1.
Highest Common Factor of 478,418,421,62 is 1
Step 1: Since 478 > 418, we apply the division lemma to 478 and 418, to get
478 = 418 x 1 + 60
Step 2: Since the reminder 418 ≠ 0, we apply division lemma to 60 and 418, to get
418 = 60 x 6 + 58
Step 3: We consider the new divisor 60 and the new remainder 58, and apply the division lemma to get
60 = 58 x 1 + 2
We consider the new divisor 58 and the new remainder 2, and apply the division lemma to get
58 = 2 x 29 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 478 and 418 is 2
Notice that 2 = HCF(58,2) = HCF(60,58) = HCF(418,60) = HCF(478,418) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 421 > 2, we apply the division lemma to 421 and 2, to get
421 = 2 x 210 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 421 is 1
Notice that 1 = HCF(2,1) = HCF(421,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 62 > 1, we apply the division lemma to 62 and 1, to get
62 = 1 x 62 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 62 is 1
Notice that 1 = HCF(62,1) .
