HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 840, 327 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 840, 327 is 3 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 840, 327 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 840, 327 is 3.
HCF(840, 327) = 3
HCF of 840, 327 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 840, 327 is 3.
Highest Common Factor of 840,327 is 3
Step 1: Since 840 > 327, we apply the division lemma to 840 and 327, to get
840 = 327 x 2 + 186
Step 2: Since the reminder 327 ≠ 0, we apply division lemma to 186 and 327, to get
327 = 186 x 1 + 141
Step 3: We consider the new divisor 186 and the new remainder 141, and apply the division lemma to get
186 = 141 x 1 + 45
We consider the new divisor 141 and the new remainder 45,and apply the division lemma to get
141 = 45 x 3 + 6
We consider the new divisor 45 and the new remainder 6,and apply the division lemma to get
45 = 6 x 7 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 840 and 327 is 3
Notice that 3 = HCF(6,3) = HCF(45,6) = HCF(141,45) = HCF(186,141) = HCF(327,186) = HCF(840,327) .
