HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 722, 779 i.e. 19 the largest integer that leaves a remainder zero for all numbers.
HCF of 722, 779 is 19 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 722, 779 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 722, 779 is 19.
HCF(722, 779) = 19
HCF of 722, 779 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 722, 779 is 19.
Highest Common Factor of 722,779 is 19
Step 1: Since 779 > 722, we apply the division lemma to 779 and 722, to get
779 = 722 x 1 + 57
Step 2: Since the reminder 722 ≠ 0, we apply division lemma to 57 and 722, to get
722 = 57 x 12 + 38
Step 3: We consider the new divisor 57 and the new remainder 38, and apply the division lemma to get
57 = 38 x 1 + 19
We consider the new divisor 38 and the new remainder 19, and apply the division lemma to get
38 = 19 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 722 and 779 is 19
Notice that 19 = HCF(38,19) = HCF(57,38) = HCF(722,57) = HCF(779,722) .
