HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 779, 909 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 779, 909 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, 909 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, 909 is 1.
HCF(779, 909) = 1
HCF of 779, 909 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, 909 is 1.
Highest Common Factor of 779,909 is 1
Step 1: Since 909 > 779, we apply the division lemma to 909 and 779, to get
909 = 779 x 1 + 130
Step 2: Since the reminder 779 ≠ 0, we apply division lemma to 130 and 779, to get
779 = 130 x 5 + 129
Step 3: We consider the new divisor 130 and the new remainder 129, and apply the division lemma to get
130 = 129 x 1 + 1
We consider the new divisor 129 and the new remainder 1, and apply the division lemma to get
129 = 1 x 129 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 779 and 909 is 1
Notice that 1 = HCF(129,1) = HCF(130,129) = HCF(779,130) = HCF(909,779) .
