HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 388, 980, 63 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 388, 980, 63 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, 980, 63 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, 980, 63 is 1.
HCF(388, 980, 63) = 1
HCF of 388, 980, 63 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, 980, 63 is 1.
Highest Common Factor of 388,980,63 is 1
Step 1: Since 980 > 388, we apply the division lemma to 980 and 388, to get
980 = 388 x 2 + 204
Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 204 and 388, to get
388 = 204 x 1 + 184
Step 3: We consider the new divisor 204 and the new remainder 184, and apply the division lemma to get
204 = 184 x 1 + 20
We consider the new divisor 184 and the new remainder 20,and apply the division lemma to get
184 = 20 x 9 + 4
We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 388 and 980 is 4
Notice that 4 = HCF(20,4) = HCF(184,20) = HCF(204,184) = HCF(388,204) = HCF(980,388) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 63 > 4, we apply the division lemma to 63 and 4, to get
63 = 4 x 15 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: 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 4 and 63 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(63,4) .
