HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 810 i.e. 90 the largest integer that leaves a remainder zero for all numbers.
HCF of 630, 810 is 90 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 630, 810 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 630, 810 is 90.
HCF(630, 810) = 90
HCF of 630, 810 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 630, 810 is 90.
Highest Common Factor of 630,810 is 90
Step 1: Since 810 > 630, we apply the division lemma to 810 and 630, to get
810 = 630 x 1 + 180
Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 180 and 630, to get
630 = 180 x 3 + 90
Step 3: We consider the new divisor 180 and the new remainder 90, and apply the division lemma to get
180 = 90 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 90, the HCF of 630 and 810 is 90
Notice that 90 = HCF(180,90) = HCF(630,180) = HCF(810,630) .
