HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 722, 253, 201, 74 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 722, 253, 201, 74 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 722, 253, 201, 74 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 722, 253, 201, 74 is 1.
HCF(722, 253, 201, 74) = 1
HCF of 722, 253, 201, 74 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 722, 253, 201, 74 is 1.
Highest Common Factor of 722,253,201,74 is 1
Step 1: Since 722 > 253, we apply the division lemma to 722 and 253, to get
722 = 253 x 2 + 216
Step 2: Since the reminder 253 ≠ 0, we apply division lemma to 216 and 253, to get
253 = 216 x 1 + 37
Step 3: We consider the new divisor 216 and the new remainder 37, and apply the division lemma to get
216 = 37 x 5 + 31
We consider the new divisor 37 and the new remainder 31,and apply the division lemma to get
37 = 31 x 1 + 6
We consider the new divisor 31 and the new remainder 6,and apply the division lemma to get
31 = 6 x 5 + 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 722 and 253 is 1
Notice that 1 = HCF(6,1) = HCF(31,6) = HCF(37,31) = HCF(216,37) = HCF(253,216) = HCF(722,253) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 201 > 1, we apply the division lemma to 201 and 1, to get
201 = 1 x 201 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 201 is 1
Notice that 1 = HCF(201,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 74 > 1, we apply the division lemma to 74 and 1, to get
74 = 1 x 74 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 74 is 1
Notice that 1 = HCF(74,1) .
