HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 746, 615, 439 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 746, 615, 439 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 746, 615, 439 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 746, 615, 439 is 1.
HCF(746, 615, 439) = 1
HCF of 746, 615, 439 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 746, 615, 439 is 1.
Highest Common Factor of 746,615,439 is 1
Step 1: Since 746 > 615, we apply the division lemma to 746 and 615, to get
746 = 615 x 1 + 131
Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 131 and 615, to get
615 = 131 x 4 + 91
Step 3: We consider the new divisor 131 and the new remainder 91, and apply the division lemma to get
131 = 91 x 1 + 40
We consider the new divisor 91 and the new remainder 40,and apply the division lemma to get
91 = 40 x 2 + 11
We consider the new divisor 40 and the new remainder 11,and apply the division lemma to get
40 = 11 x 3 + 7
We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get
11 = 7 x 1 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 746 and 615 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(40,11) = HCF(91,40) = HCF(131,91) = HCF(615,131) = HCF(746,615) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 439 > 1, we apply the division lemma to 439 and 1, to get
439 = 1 x 439 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 439 is 1
Notice that 1 = HCF(439,1) .
