HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 909, 669, 948 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 909, 669, 948 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 909, 669, 948 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 909, 669, 948 is 3.
HCF(909, 669, 948) = 3
HCF of 909, 669, 948 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 909, 669, 948 is 3.
Highest Common Factor of 909,669,948 is 3
Step 1: Since 909 > 669, we apply the division lemma to 909 and 669, to get
909 = 669 x 1 + 240
Step 2: Since the reminder 669 ≠ 0, we apply division lemma to 240 and 669, to get
669 = 240 x 2 + 189
Step 3: We consider the new divisor 240 and the new remainder 189, and apply the division lemma to get
240 = 189 x 1 + 51
We consider the new divisor 189 and the new remainder 51,and apply the division lemma to get
189 = 51 x 3 + 36
We consider the new divisor 51 and the new remainder 36,and apply the division lemma to get
51 = 36 x 1 + 15
We consider the new divisor 36 and the new remainder 15,and apply the division lemma to get
36 = 15 x 2 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 909 and 669 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(36,15) = HCF(51,36) = HCF(189,51) = HCF(240,189) = HCF(669,240) = HCF(909,669) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 948 > 3, we apply the division lemma to 948 and 3, to get
948 = 3 x 316 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 948 is 3
Notice that 3 = HCF(948,3) .
