HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 777, 328 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 777, 328 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 777, 328 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 777, 328 is 1.
HCF(777, 328) = 1
HCF of 777, 328 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 777, 328 is 1.
Highest Common Factor of 777,328 is 1
Step 1: Since 777 > 328, we apply the division lemma to 777 and 328, to get
777 = 328 x 2 + 121
Step 2: Since the reminder 328 ≠ 0, we apply division lemma to 121 and 328, to get
328 = 121 x 2 + 86
Step 3: We consider the new divisor 121 and the new remainder 86, and apply the division lemma to get
121 = 86 x 1 + 35
We consider the new divisor 86 and the new remainder 35,and apply the division lemma to get
86 = 35 x 2 + 16
We consider the new divisor 35 and the new remainder 16,and apply the division lemma to get
35 = 16 x 2 + 3
We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get
16 = 3 x 5 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 777 and 328 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(35,16) = HCF(86,35) = HCF(121,86) = HCF(328,121) = HCF(777,328) .
