HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 672, 939, 204 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 672, 939, 204 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 672, 939, 204 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 672, 939, 204 is 3.
HCF(672, 939, 204) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 672, 939, 204 is 3.
Step 1: Since 939 > 672, we apply the division lemma to 939 and 672, to get
939 = 672 x 1 + 267
Step 2: Since the reminder 672 ≠ 0, we apply division lemma to 267 and 672, to get
672 = 267 x 2 + 138
Step 3: We consider the new divisor 267 and the new remainder 138, and apply the division lemma to get
267 = 138 x 1 + 129
We consider the new divisor 138 and the new remainder 129,and apply the division lemma to get
138 = 129 x 1 + 9
We consider the new divisor 129 and the new remainder 9,and apply the division lemma to get
129 = 9 x 14 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 672 and 939 is 3
Notice that 3 = HCF(9,3) = HCF(129,9) = HCF(138,129) = HCF(267,138) = HCF(672,267) = HCF(939,672) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 204 > 3, we apply the division lemma to 204 and 3, to get
204 = 3 x 68 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 204 is 3
Notice that 3 = HCF(204,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
