HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 202, 930 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 202, 930 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, 930 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, 930 is 2.
HCF(202, 930) = 2
HCF of 202, 930 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, 930 is 2.
Highest Common Factor of 202,930 is 2
Step 1: Since 930 > 202, we apply the division lemma to 930 and 202, to get
930 = 202 x 4 + 122
Step 2: Since the reminder 202 ≠ 0, we apply division lemma to 122 and 202, to get
202 = 122 x 1 + 80
Step 3: We consider the new divisor 122 and the new remainder 80, and apply the division lemma to get
122 = 80 x 1 + 42
We consider the new divisor 80 and the new remainder 42,and apply the division lemma to get
80 = 42 x 1 + 38
We consider the new divisor 42 and the new remainder 38,and apply the division lemma to get
42 = 38 x 1 + 4
We consider the new divisor 38 and the new remainder 4,and apply the division lemma to get
38 = 4 x 9 + 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 930 is 2
Notice that 2 = HCF(4,2) = HCF(38,4) = HCF(42,38) = HCF(80,42) = HCF(122,80) = HCF(202,122) = HCF(930,202) .
