HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 396, 684, 909 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 396, 684, 909 is 9 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 396, 684, 909 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 396, 684, 909 is 9.
HCF(396, 684, 909) = 9
HCF of 396, 684, 909 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 396, 684, 909 is 9.
Highest Common Factor of 396,684,909 is 9
Step 1: Since 684 > 396, we apply the division lemma to 684 and 396, to get
684 = 396 x 1 + 288
Step 2: Since the reminder 396 ≠ 0, we apply division lemma to 288 and 396, to get
396 = 288 x 1 + 108
Step 3: We consider the new divisor 288 and the new remainder 108, and apply the division lemma to get
288 = 108 x 2 + 72
We consider the new divisor 108 and the new remainder 72,and apply the division lemma to get
108 = 72 x 1 + 36
We consider the new divisor 72 and the new remainder 36,and apply the division lemma to get
72 = 36 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 36, the HCF of 396 and 684 is 36
Notice that 36 = HCF(72,36) = HCF(108,72) = HCF(288,108) = HCF(396,288) = HCF(684,396) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 909 > 36, we apply the division lemma to 909 and 36, to get
909 = 36 x 25 + 9
Step 2: Since the reminder 36 ≠ 0, we apply division lemma to 9 and 36, to get
36 = 9 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 36 and 909 is 9
Notice that 9 = HCF(36,9) = HCF(909,36) .
