HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 744, 969, 675 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 744, 969, 675 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 744, 969, 675 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 744, 969, 675 is 3.
HCF(744, 969, 675) = 3
HCF of 744, 969, 675 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 744, 969, 675 is 3.
Highest Common Factor of 744,969,675 is 3
Step 1: Since 969 > 744, we apply the division lemma to 969 and 744, to get
969 = 744 x 1 + 225
Step 2: Since the reminder 744 ≠ 0, we apply division lemma to 225 and 744, to get
744 = 225 x 3 + 69
Step 3: We consider the new divisor 225 and the new remainder 69, and apply the division lemma to get
225 = 69 x 3 + 18
We consider the new divisor 69 and the new remainder 18,and apply the division lemma to get
69 = 18 x 3 + 15
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 744 and 969 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(69,18) = HCF(225,69) = HCF(744,225) = HCF(969,744) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 675 > 3, we apply the division lemma to 675 and 3, to get
675 = 3 x 225 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 675 is 3
Notice that 3 = HCF(675,3) .
