HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 617, 819 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 617, 819 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, 617, 819 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, 617, 819 is 1.
HCF(980, 617, 819) = 1
HCF of 980, 617, 819 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, 617, 819 is 1.
Highest Common Factor of 980,617,819 is 1
Step 1: Since 980 > 617, we apply the division lemma to 980 and 617, to get
980 = 617 x 1 + 363
Step 2: Since the reminder 617 ≠ 0, we apply division lemma to 363 and 617, to get
617 = 363 x 1 + 254
Step 3: We consider the new divisor 363 and the new remainder 254, and apply the division lemma to get
363 = 254 x 1 + 109
We consider the new divisor 254 and the new remainder 109,and apply the division lemma to get
254 = 109 x 2 + 36
We consider the new divisor 109 and the new remainder 36,and apply the division lemma to get
109 = 36 x 3 + 1
We consider the new divisor 36 and the new remainder 1,and apply the division lemma to get
36 = 1 x 36 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 980 and 617 is 1
Notice that 1 = HCF(36,1) = HCF(109,36) = HCF(254,109) = HCF(363,254) = HCF(617,363) = HCF(980,617) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 819 > 1, we apply the division lemma to 819 and 1, to get
819 = 1 x 819 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 819 is 1
Notice that 1 = HCF(819,1) .
