HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 495, 872 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 495, 872 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, 872 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, 872 is 1.
HCF(495, 872) = 1
HCF of 495, 872 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, 872 is 1.
Highest Common Factor of 495,872 is 1
Step 1: Since 872 > 495, we apply the division lemma to 872 and 495, to get
872 = 495 x 1 + 377
Step 2: Since the reminder 495 ≠ 0, we apply division lemma to 377 and 495, to get
495 = 377 x 1 + 118
Step 3: We consider the new divisor 377 and the new remainder 118, and apply the division lemma to get
377 = 118 x 3 + 23
We consider the new divisor 118 and the new remainder 23,and apply the division lemma to get
118 = 23 x 5 + 3
We consider the new divisor 23 and the new remainder 3,and apply the division lemma to get
23 = 3 x 7 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 495 and 872 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(23,3) = HCF(118,23) = HCF(377,118) = HCF(495,377) = HCF(872,495) .
