HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 923, 202, 418 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 923, 202, 418 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 923, 202, 418 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 923, 202, 418 is 1.
HCF(923, 202, 418) = 1
HCF of 923, 202, 418 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 923, 202, 418 is 1.
Highest Common Factor of 923,202,418 is 1
Step 1: Since 923 > 202, we apply the division lemma to 923 and 202, to get
923 = 202 x 4 + 115
Step 2: Since the reminder 202 ≠ 0, we apply division lemma to 115 and 202, to get
202 = 115 x 1 + 87
Step 3: We consider the new divisor 115 and the new remainder 87, and apply the division lemma to get
115 = 87 x 1 + 28
We consider the new divisor 87 and the new remainder 28,and apply the division lemma to get
87 = 28 x 3 + 3
We consider the new divisor 28 and the new remainder 3,and apply the division lemma to get
28 = 3 x 9 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 923 and 202 is 1
Notice that 1 = HCF(3,1) = HCF(28,3) = HCF(87,28) = HCF(115,87) = HCF(202,115) = HCF(923,202) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 418 > 1, we apply the division lemma to 418 and 1, to get
418 = 1 x 418 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 418 is 1
Notice that 1 = HCF(418,1) .
