HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 44, 769, 121 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 44, 769, 121 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 44, 769, 121 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 44, 769, 121 is 1.
HCF(44, 769, 121) = 1
HCF of 44, 769, 121 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 44, 769, 121 is 1.
Highest Common Factor of 44,769,121 is 1
Step 1: Since 769 > 44, we apply the division lemma to 769 and 44, to get
769 = 44 x 17 + 21
Step 2: Since the reminder 44 ≠ 0, we apply division lemma to 21 and 44, to get
44 = 21 x 2 + 2
Step 3: We consider the new divisor 21 and the new remainder 2, and apply the division lemma to get
21 = 2 x 10 + 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 44 and 769 is 1
Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(44,21) = HCF(769,44) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 121 > 1, we apply the division lemma to 121 and 1, to get
121 = 1 x 121 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 121 is 1
Notice that 1 = HCF(121,1) .
