HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 253, 430, 222 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 253, 430, 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 253, 430, 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 253, 430, 222 is 1.
HCF(253, 430, 222) = 1
HCF of 253, 430, 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 253, 430, 222 is 1.
Highest Common Factor of 253,430,222 is 1
Step 1: Since 430 > 253, we apply the division lemma to 430 and 253, to get
430 = 253 x 1 + 177
Step 2: Since the reminder 253 ≠ 0, we apply division lemma to 177 and 253, to get
253 = 177 x 1 + 76
Step 3: We consider the new divisor 177 and the new remainder 76, and apply the division lemma to get
177 = 76 x 2 + 25
We consider the new divisor 76 and the new remainder 25,and apply the division lemma to get
76 = 25 x 3 + 1
We consider the new divisor 25 and the new remainder 1,and apply the division lemma to get
25 = 1 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 253 and 430 is 1
Notice that 1 = HCF(25,1) = HCF(76,25) = HCF(177,76) = HCF(253,177) = HCF(430,253) .
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) .
