HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 87, 69, 99, 327 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 87, 69, 99, 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 87, 69, 99, 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 87, 69, 99, 327 is 3.
HCF(87, 69, 99, 327) = 3
HCF of 87, 69, 99, 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 87, 69, 99, 327 is 3.
Highest Common Factor of 87,69,99,327 is 3
Step 1: Since 87 > 69, we apply the division lemma to 87 and 69, to get
87 = 69 x 1 + 18
Step 2: Since the reminder 69 ≠ 0, we apply division lemma to 18 and 69, to get
69 = 18 x 3 + 15
Step 3: We consider the new divisor 18 and the new remainder 15, and apply the division lemma to get
18 = 15 x 1 + 3
We consider the new divisor 15 and the new remainder 3, and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 87 and 69 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(69,18) = HCF(87,69) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 99 > 3, we apply the division lemma to 99 and 3, to get
99 = 3 x 33 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 99 is 3
Notice that 3 = HCF(99,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 327 > 3, we apply the division lemma to 327 and 3, to get
327 = 3 x 109 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 327 is 3
Notice that 3 = HCF(327,3) .
