HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 495, 743 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 495, 743 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 495, 743 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 495, 743 is 1.
HCF(495, 743) = 1
HCF of 495, 743 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 495, 743 is 1.
Highest Common Factor of 495,743 is 1
Step 1: Since 743 > 495, we apply the division lemma to 743 and 495, to get
743 = 495 x 1 + 248
Step 2: Since the reminder 495 ≠ 0, we apply division lemma to 248 and 495, to get
495 = 248 x 1 + 247
Step 3: We consider the new divisor 248 and the new remainder 247, and apply the division lemma to get
248 = 247 x 1 + 1
We consider the new divisor 247 and the new remainder 1, and apply the division lemma to get
247 = 1 x 247 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 495 and 743 is 1
Notice that 1 = HCF(247,1) = HCF(248,247) = HCF(495,248) = HCF(743,495) .
