HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 621, 327, 336 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 621, 327, 336 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 621, 327, 336 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 621, 327, 336 is 3.
HCF(621, 327, 336) = 3
HCF of 621, 327, 336 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 621, 327, 336 is 3.
Highest Common Factor of 621,327,336 is 3
Step 1: Since 621 > 327, we apply the division lemma to 621 and 327, to get
621 = 327 x 1 + 294
Step 2: Since the reminder 327 ≠ 0, we apply division lemma to 294 and 327, to get
327 = 294 x 1 + 33
Step 3: We consider the new divisor 294 and the new remainder 33, and apply the division lemma to get
294 = 33 x 8 + 30
We consider the new divisor 33 and the new remainder 30,and apply the division lemma to get
33 = 30 x 1 + 3
We consider the new divisor 30 and the new remainder 3,and apply the division lemma to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 621 and 327 is 3
Notice that 3 = HCF(30,3) = HCF(33,30) = HCF(294,33) = HCF(327,294) = HCF(621,327) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 336 > 3, we apply the division lemma to 336 and 3, to get
336 = 3 x 112 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 336 is 3
Notice that 3 = HCF(336,3) .
