HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 779, 647 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 779, 647 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 779, 647 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 779, 647 is 1.
HCF(779, 647) = 1
HCF of 779, 647 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 779, 647 is 1.
Highest Common Factor of 779,647 is 1
Step 1: Since 779 > 647, we apply the division lemma to 779 and 647, to get
779 = 647 x 1 + 132
Step 2: Since the reminder 647 ≠ 0, we apply division lemma to 132 and 647, to get
647 = 132 x 4 + 119
Step 3: We consider the new divisor 132 and the new remainder 119, and apply the division lemma to get
132 = 119 x 1 + 13
We consider the new divisor 119 and the new remainder 13,and apply the division lemma to get
119 = 13 x 9 + 2
We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get
13 = 2 x 6 + 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 779 and 647 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(119,13) = HCF(132,119) = HCF(647,132) = HCF(779,647) .
