HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 785, 137, 65 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 785, 137, 65 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 785, 137, 65 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 785, 137, 65 is 1.
HCF(785, 137, 65) = 1
HCF of 785, 137, 65 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 785, 137, 65 is 1.
Highest Common Factor of 785,137,65 is 1
Step 1: Since 785 > 137, we apply the division lemma to 785 and 137, to get
785 = 137 x 5 + 100
Step 2: Since the reminder 137 ≠ 0, we apply division lemma to 100 and 137, to get
137 = 100 x 1 + 37
Step 3: We consider the new divisor 100 and the new remainder 37, and apply the division lemma to get
100 = 37 x 2 + 26
We consider the new divisor 37 and the new remainder 26,and apply the division lemma to get
37 = 26 x 1 + 11
We consider the new divisor 26 and the new remainder 11,and apply the division lemma to get
26 = 11 x 2 + 4
We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get
11 = 4 x 2 + 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 785 and 137 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(26,11) = HCF(37,26) = HCF(100,37) = HCF(137,100) = HCF(785,137) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 65 > 1, we apply the division lemma to 65 and 1, to get
65 = 1 x 65 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 65 is 1
Notice that 1 = HCF(65,1) .
