HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2454, 662 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 2454, 662 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 2454, 662 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 2454, 662 is 2.
HCF(2454, 662) = 2
HCF of 2454, 662 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 2454, 662 is 2.
Highest Common Factor of 2454,662 is 2
Step 1: Since 2454 > 662, we apply the division lemma to 2454 and 662, to get
2454 = 662 x 3 + 468
Step 2: Since the reminder 662 ≠ 0, we apply division lemma to 468 and 662, to get
662 = 468 x 1 + 194
Step 3: We consider the new divisor 468 and the new remainder 194, and apply the division lemma to get
468 = 194 x 2 + 80
We consider the new divisor 194 and the new remainder 80,and apply the division lemma to get
194 = 80 x 2 + 34
We consider the new divisor 80 and the new remainder 34,and apply the division lemma to get
80 = 34 x 2 + 12
We consider the new divisor 34 and the new remainder 12,and apply the division lemma to get
34 = 12 x 2 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2454 and 662 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(34,12) = HCF(80,34) = HCF(194,80) = HCF(468,194) = HCF(662,468) = HCF(2454,662) .
