HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 829, 931 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 829, 931 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 980, 829, 931 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 980, 829, 931 is 1.
HCF(980, 829, 931) = 1
HCF of 980, 829, 931 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 980, 829, 931 is 1.
Highest Common Factor of 980,829,931 is 1
Step 1: Since 980 > 829, we apply the division lemma to 980 and 829, to get
980 = 829 x 1 + 151
Step 2: Since the reminder 829 ≠ 0, we apply division lemma to 151 and 829, to get
829 = 151 x 5 + 74
Step 3: We consider the new divisor 151 and the new remainder 74, and apply the division lemma to get
151 = 74 x 2 + 3
We consider the new divisor 74 and the new remainder 3,and apply the division lemma to get
74 = 3 x 24 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 980 and 829 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(74,3) = HCF(151,74) = HCF(829,151) = HCF(980,829) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 931 > 1, we apply the division lemma to 931 and 1, to get
931 = 1 x 931 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 931 is 1
Notice that 1 = HCF(931,1) .
