HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 603, 769, 127 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 603, 769, 127 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 603, 769, 127 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 603, 769, 127 is 1.
HCF(603, 769, 127) = 1
HCF of 603, 769, 127 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 603, 769, 127 is 1.
Highest Common Factor of 603,769,127 is 1
Step 1: Since 769 > 603, we apply the division lemma to 769 and 603, to get
769 = 603 x 1 + 166
Step 2: Since the reminder 603 ≠ 0, we apply division lemma to 166 and 603, to get
603 = 166 x 3 + 105
Step 3: We consider the new divisor 166 and the new remainder 105, and apply the division lemma to get
166 = 105 x 1 + 61
We consider the new divisor 105 and the new remainder 61,and apply the division lemma to get
105 = 61 x 1 + 44
We consider the new divisor 61 and the new remainder 44,and apply the division lemma to get
61 = 44 x 1 + 17
We consider the new divisor 44 and the new remainder 17,and apply the division lemma to get
44 = 17 x 2 + 10
We consider the new divisor 17 and the new remainder 10,and apply the division lemma to get
17 = 10 x 1 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 603 and 769 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(44,17) = HCF(61,44) = HCF(105,61) = HCF(166,105) = HCF(603,166) = HCF(769,603) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 127 > 1, we apply the division lemma to 127 and 1, to get
127 = 1 x 127 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 127 is 1
Notice that 1 = HCF(127,1) .
