HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 388, 78495 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 388, 78495 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 388, 78495 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 388, 78495 is 1.
HCF(388, 78495) = 1
HCF of 388, 78495 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 388, 78495 is 1.
Highest Common Factor of 388,78495 is 1
Step 1: Since 78495 > 388, we apply the division lemma to 78495 and 388, to get
78495 = 388 x 202 + 119
Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 119 and 388, to get
388 = 119 x 3 + 31
Step 3: We consider the new divisor 119 and the new remainder 31, and apply the division lemma to get
119 = 31 x 3 + 26
We consider the new divisor 31 and the new remainder 26,and apply the division lemma to get
31 = 26 x 1 + 5
We consider the new divisor 26 and the new remainder 5,and apply the division lemma to get
26 = 5 x 5 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 388 and 78495 is 1
Notice that 1 = HCF(5,1) = HCF(26,5) = HCF(31,26) = HCF(119,31) = HCF(388,119) = HCF(78495,388) .
