HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 434, 779, 121 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 434, 779, 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 434, 779, 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 434, 779, 121 is 1.
HCF(434, 779, 121) = 1
HCF of 434, 779, 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 434, 779, 121 is 1.
Highest Common Factor of 434,779,121 is 1
Step 1: Since 779 > 434, we apply the division lemma to 779 and 434, to get
779 = 434 x 1 + 345
Step 2: Since the reminder 434 ≠ 0, we apply division lemma to 345 and 434, to get
434 = 345 x 1 + 89
Step 3: We consider the new divisor 345 and the new remainder 89, and apply the division lemma to get
345 = 89 x 3 + 78
We consider the new divisor 89 and the new remainder 78,and apply the division lemma to get
89 = 78 x 1 + 11
We consider the new divisor 78 and the new remainder 11,and apply the division lemma to get
78 = 11 x 7 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 434 and 779 is 1
Notice that 1 = HCF(11,1) = HCF(78,11) = HCF(89,78) = HCF(345,89) = HCF(434,345) = HCF(779,434) .
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) .
