HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 705, 495 i.e. 15 the largest integer that leaves a remainder zero for all numbers.
HCF of 705, 495 is 15 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 705, 495 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 705, 495 is 15.
HCF(705, 495) = 15
HCF of 705, 495 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 705, 495 is 15.
Highest Common Factor of 705,495 is 15
Step 1: Since 705 > 495, we apply the division lemma to 705 and 495, to get
705 = 495 x 1 + 210
Step 2: Since the reminder 495 ≠ 0, we apply division lemma to 210 and 495, to get
495 = 210 x 2 + 75
Step 3: We consider the new divisor 210 and the new remainder 75, and apply the division lemma to get
210 = 75 x 2 + 60
We consider the new divisor 75 and the new remainder 60,and apply the division lemma to get
75 = 60 x 1 + 15
We consider the new divisor 60 and the new remainder 15,and apply the division lemma to get
60 = 15 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 705 and 495 is 15
Notice that 15 = HCF(60,15) = HCF(75,60) = HCF(210,75) = HCF(495,210) = HCF(705,495) .
