HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 971, 752, 120 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 971, 752, 120 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 971, 752, 120 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 971, 752, 120 is 1.
HCF(971, 752, 120) = 1
HCF of 971, 752, 120 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 971, 752, 120 is 1.
Highest Common Factor of 971,752,120 is 1
Step 1: Since 971 > 752, we apply the division lemma to 971 and 752, to get
971 = 752 x 1 + 219
Step 2: Since the reminder 752 ≠ 0, we apply division lemma to 219 and 752, to get
752 = 219 x 3 + 95
Step 3: We consider the new divisor 219 and the new remainder 95, and apply the division lemma to get
219 = 95 x 2 + 29
We consider the new divisor 95 and the new remainder 29,and apply the division lemma to get
95 = 29 x 3 + 8
We consider the new divisor 29 and the new remainder 8,and apply the division lemma to get
29 = 8 x 3 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 971 and 752 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(29,8) = HCF(95,29) = HCF(219,95) = HCF(752,219) = HCF(971,752) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 120 > 1, we apply the division lemma to 120 and 1, to get
120 = 1 x 120 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 120 is 1
Notice that 1 = HCF(120,1) .
