HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 979, 729 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 979, 729 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 979, 729 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 979, 729 is 1.
HCF(979, 729) = 1
HCF of 979, 729 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 979, 729 is 1.
Highest Common Factor of 979,729 is 1
Step 1: Since 979 > 729, we apply the division lemma to 979 and 729, to get
979 = 729 x 1 + 250
Step 2: Since the reminder 729 ≠ 0, we apply division lemma to 250 and 729, to get
729 = 250 x 2 + 229
Step 3: We consider the new divisor 250 and the new remainder 229, and apply the division lemma to get
250 = 229 x 1 + 21
We consider the new divisor 229 and the new remainder 21,and apply the division lemma to get
229 = 21 x 10 + 19
We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get
21 = 19 x 1 + 2
We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get
19 = 2 x 9 + 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 979 and 729 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(229,21) = HCF(250,229) = HCF(729,250) = HCF(979,729) .
