HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 873, 630 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 873, 630 is 9 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 873, 630 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 873, 630 is 9.
HCF(873, 630) = 9
HCF of 873, 630 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 873, 630 is 9.
Highest Common Factor of 873,630 is 9
Step 1: Since 873 > 630, we apply the division lemma to 873 and 630, to get
873 = 630 x 1 + 243
Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 243 and 630, to get
630 = 243 x 2 + 144
Step 3: We consider the new divisor 243 and the new remainder 144, and apply the division lemma to get
243 = 144 x 1 + 99
We consider the new divisor 144 and the new remainder 99,and apply the division lemma to get
144 = 99 x 1 + 45
We consider the new divisor 99 and the new remainder 45,and apply the division lemma to get
99 = 45 x 2 + 9
We consider the new divisor 45 and the new remainder 9,and apply the division lemma to get
45 = 9 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 873 and 630 is 9
Notice that 9 = HCF(45,9) = HCF(99,45) = HCF(144,99) = HCF(243,144) = HCF(630,243) = HCF(873,630) .
