HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 165, 658, 503 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 165, 658, 503 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 165, 658, 503 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 165, 658, 503 is 1.
HCF(165, 658, 503) = 1
HCF of 165, 658, 503 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 165, 658, 503 is 1.
Highest Common Factor of 165,658,503 is 1
Step 1: Since 658 > 165, we apply the division lemma to 658 and 165, to get
658 = 165 x 3 + 163
Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 163 and 165, to get
165 = 163 x 1 + 2
Step 3: We consider the new divisor 163 and the new remainder 2, and apply the division lemma to get
163 = 2 x 81 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 165 and 658 is 1
Notice that 1 = HCF(2,1) = HCF(163,2) = HCF(165,163) = HCF(658,165) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 503 > 1, we apply the division lemma to 503 and 1, to get
503 = 1 x 503 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 503 is 1
Notice that 1 = HCF(503,1) .
