HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 734, 427, 945 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 734, 427, 945 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 734, 427, 945 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 734, 427, 945 is 1.
HCF(734, 427, 945) = 1
HCF of 734, 427, 945 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 734, 427, 945 is 1.
Highest Common Factor of 734,427,945 is 1
Step 1: Since 734 > 427, we apply the division lemma to 734 and 427, to get
734 = 427 x 1 + 307
Step 2: Since the reminder 427 ≠ 0, we apply division lemma to 307 and 427, to get
427 = 307 x 1 + 120
Step 3: We consider the new divisor 307 and the new remainder 120, and apply the division lemma to get
307 = 120 x 2 + 67
We consider the new divisor 120 and the new remainder 67,and apply the division lemma to get
120 = 67 x 1 + 53
We consider the new divisor 67 and the new remainder 53,and apply the division lemma to get
67 = 53 x 1 + 14
We consider the new divisor 53 and the new remainder 14,and apply the division lemma to get
53 = 14 x 3 + 11
We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get
14 = 11 x 1 + 3
We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get
11 = 3 x 3 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 734 and 427 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(53,14) = HCF(67,53) = HCF(120,67) = HCF(307,120) = HCF(427,307) = HCF(734,427) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 945 > 1, we apply the division lemma to 945 and 1, to get
945 = 1 x 945 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 945 is 1
Notice that 1 = HCF(945,1) .
