HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 774, 894, 45 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 774, 894, 45 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 774, 894, 45 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 774, 894, 45 is 3.
HCF(774, 894, 45) = 3
HCF of 774, 894, 45 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 774, 894, 45 is 3.
Highest Common Factor of 774,894,45 is 3
Step 1: Since 894 > 774, we apply the division lemma to 894 and 774, to get
894 = 774 x 1 + 120
Step 2: Since the reminder 774 ≠ 0, we apply division lemma to 120 and 774, to get
774 = 120 x 6 + 54
Step 3: We consider the new divisor 120 and the new remainder 54, and apply the division lemma to get
120 = 54 x 2 + 12
We consider the new divisor 54 and the new remainder 12,and apply the division lemma to get
54 = 12 x 4 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 774 and 894 is 6
Notice that 6 = HCF(12,6) = HCF(54,12) = HCF(120,54) = HCF(774,120) = HCF(894,774) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 45 > 6, we apply the division lemma to 45 and 6, to get
45 = 6 x 7 + 3
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 3 and 6, 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 6 and 45 is 3
Notice that 3 = HCF(6,3) = HCF(45,6) .
