HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 188, 492 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 188, 492 is 4 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 188, 492 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 188, 492 is 4.
HCF(188, 492) = 4
HCF of 188, 492 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 188, 492 is 4.
Highest Common Factor of 188,492 is 4
Step 1: Since 492 > 188, we apply the division lemma to 492 and 188, to get
492 = 188 x 2 + 116
Step 2: Since the reminder 188 ≠ 0, we apply division lemma to 116 and 188, to get
188 = 116 x 1 + 72
Step 3: We consider the new divisor 116 and the new remainder 72, and apply the division lemma to get
116 = 72 x 1 + 44
We consider the new divisor 72 and the new remainder 44,and apply the division lemma to get
72 = 44 x 1 + 28
We consider the new divisor 44 and the new remainder 28,and apply the division lemma to get
44 = 28 x 1 + 16
We consider the new divisor 28 and the new remainder 16,and apply the division lemma to get
28 = 16 x 1 + 12
We consider the new divisor 16 and the new remainder 12,and apply the division lemma to get
16 = 12 x 1 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 188 and 492 is 4
Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(28,16) = HCF(44,28) = HCF(72,44) = HCF(116,72) = HCF(188,116) = HCF(492,188) .
