HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 202, 2144 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 202, 2144 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 202, 2144 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 202, 2144 is 2.
HCF(202, 2144) = 2
HCF of 202, 2144 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 202, 2144 is 2.
Highest Common Factor of 202,2144 is 2
Step 1: Since 2144 > 202, we apply the division lemma to 2144 and 202, to get
2144 = 202 x 10 + 124
Step 2: Since the reminder 202 ≠ 0, we apply division lemma to 124 and 202, to get
202 = 124 x 1 + 78
Step 3: We consider the new divisor 124 and the new remainder 78, and apply the division lemma to get
124 = 78 x 1 + 46
We consider the new divisor 78 and the new remainder 46,and apply the division lemma to get
78 = 46 x 1 + 32
We consider the new divisor 46 and the new remainder 32,and apply the division lemma to get
46 = 32 x 1 + 14
We consider the new divisor 32 and the new remainder 14,and apply the division lemma to get
32 = 14 x 2 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 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 202 and 2144 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(32,14) = HCF(46,32) = HCF(78,46) = HCF(124,78) = HCF(202,124) = HCF(2144,202) .
