HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 770, 452, 957 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 770, 452, 957 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 770, 452, 957 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 770, 452, 957 is 1.
HCF(770, 452, 957) = 1
HCF of 770, 452, 957 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 770, 452, 957 is 1.
Highest Common Factor of 770,452,957 is 1
Step 1: Since 770 > 452, we apply the division lemma to 770 and 452, to get
770 = 452 x 1 + 318
Step 2: Since the reminder 452 ≠ 0, we apply division lemma to 318 and 452, to get
452 = 318 x 1 + 134
Step 3: We consider the new divisor 318 and the new remainder 134, and apply the division lemma to get
318 = 134 x 2 + 50
We consider the new divisor 134 and the new remainder 50,and apply the division lemma to get
134 = 50 x 2 + 34
We consider the new divisor 50 and the new remainder 34,and apply the division lemma to get
50 = 34 x 1 + 16
We consider the new divisor 34 and the new remainder 16,and apply the division lemma to get
34 = 16 x 2 + 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 770 and 452 is 2
Notice that 2 = HCF(16,2) = HCF(34,16) = HCF(50,34) = HCF(134,50) = HCF(318,134) = HCF(452,318) = HCF(770,452) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 957 > 2, we apply the division lemma to 957 and 2, to get
957 = 2 x 478 + 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 957 is 1
Notice that 1 = HCF(2,1) = HCF(957,2) .
