HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 707, 122, 731 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 707, 122, 731 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 707, 122, 731 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 707, 122, 731 is 1.
HCF(707, 122, 731) = 1
HCF of 707, 122, 731 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 707, 122, 731 is 1.
Highest Common Factor of 707,122,731 is 1
Step 1: Since 707 > 122, we apply the division lemma to 707 and 122, to get
707 = 122 x 5 + 97
Step 2: Since the reminder 122 ≠ 0, we apply division lemma to 97 and 122, to get
122 = 97 x 1 + 25
Step 3: We consider the new divisor 97 and the new remainder 25, and apply the division lemma to get
97 = 25 x 3 + 22
We consider the new divisor 25 and the new remainder 22,and apply the division lemma to get
25 = 22 x 1 + 3
We consider the new divisor 22 and the new remainder 3,and apply the division lemma to get
22 = 3 x 7 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 707 and 122 is 1
Notice that 1 = HCF(3,1) = HCF(22,3) = HCF(25,22) = HCF(97,25) = HCF(122,97) = HCF(707,122) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 731 > 1, we apply the division lemma to 731 and 1, to get
731 = 1 x 731 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 731 is 1
Notice that 1 = HCF(731,1) .
