HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 63, 220, 938, 164 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 63, 220, 938, 164 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 63, 220, 938, 164 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 63, 220, 938, 164 is 1.
HCF(63, 220, 938, 164) = 1
HCF of 63, 220, 938, 164 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 63, 220, 938, 164 is 1.
Highest Common Factor of 63,220,938,164 is 1
Step 1: Since 220 > 63, we apply the division lemma to 220 and 63, to get
220 = 63 x 3 + 31
Step 2: Since the reminder 63 ≠ 0, we apply division lemma to 31 and 63, to get
63 = 31 x 2 + 1
Step 3: We consider the new divisor 31 and the new remainder 1, and apply the division lemma to get
31 = 1 x 31 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 63 and 220 is 1
Notice that 1 = HCF(31,1) = HCF(63,31) = HCF(220,63) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 938 > 1, we apply the division lemma to 938 and 1, to get
938 = 1 x 938 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 938 is 1
Notice that 1 = HCF(938,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 164 > 1, we apply the division lemma to 164 and 1, to get
164 = 1 x 164 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 164 is 1
Notice that 1 = HCF(164,1) .
