HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 339, 909, 402, 127 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 339, 909, 402, 127 is 1 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 339, 909, 402, 127 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 339, 909, 402, 127 is 1.
HCF(339, 909, 402, 127) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 339, 909, 402, 127 is 1.
Step 1: Since 909 > 339, we apply the division lemma to 909 and 339, to get
909 = 339 x 2 + 231
Step 2: Since the reminder 339 ≠ 0, we apply division lemma to 231 and 339, to get
339 = 231 x 1 + 108
Step 3: We consider the new divisor 231 and the new remainder 108, and apply the division lemma to get
231 = 108 x 2 + 15
We consider the new divisor 108 and the new remainder 15,and apply the division lemma to get
108 = 15 x 7 + 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 339 and 909 is 3
Notice that 3 = HCF(15,3) = HCF(108,15) = HCF(231,108) = HCF(339,231) = HCF(909,339) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 402 > 3, we apply the division lemma to 402 and 3, to get
402 = 3 x 134 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 402 is 3
Notice that 3 = HCF(402,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 127 > 3, we apply the division lemma to 127 and 3, to get
127 = 3 x 42 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 127 is 1
Notice that 1 = HCF(3,1) = HCF(127,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
