HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 722, 634, 247 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 722, 634, 247 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, 634, 247 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, 634, 247 is 1.
HCF(722, 634, 247) = 1
HCF of 722, 634, 247 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, 634, 247 is 1.
Highest Common Factor of 722,634,247 is 1
Step 1: Since 722 > 634, we apply the division lemma to 722 and 634, to get
722 = 634 x 1 + 88
Step 2: Since the reminder 634 ≠ 0, we apply division lemma to 88 and 634, to get
634 = 88 x 7 + 18
Step 3: We consider the new divisor 88 and the new remainder 18, and apply the division lemma to get
88 = 18 x 4 + 16
We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get
18 = 16 x 1 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 722 and 634 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(88,18) = HCF(634,88) = HCF(722,634) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 247 > 2, we apply the division lemma to 247 and 2, to get
247 = 2 x 123 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 247 is 1
Notice that 1 = HCF(2,1) = HCF(247,2) .
