HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 238, 61, 222 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 238, 61, 222 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 238, 61, 222 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 238, 61, 222 is 1.
HCF(238, 61, 222) = 1
HCF of 238, 61, 222 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 238, 61, 222 is 1.
Highest Common Factor of 238,61,222 is 1
Step 1: Since 238 > 61, we apply the division lemma to 238 and 61, to get
238 = 61 x 3 + 55
Step 2: Since the reminder 61 ≠ 0, we apply division lemma to 55 and 61, to get
61 = 55 x 1 + 6
Step 3: We consider the new divisor 55 and the new remainder 6, and apply the division lemma to get
55 = 6 x 9 + 1
We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 238 and 61 is 1
Notice that 1 = HCF(6,1) = HCF(55,6) = HCF(61,55) = HCF(238,61) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 222 > 1, we apply the division lemma to 222 and 1, to get
222 = 1 x 222 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 222 is 1
Notice that 1 = HCF(222,1) .
