HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 957, 625, 863, 145 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 957, 625, 863, 145 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 957, 625, 863, 145 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 957, 625, 863, 145 is 1.
HCF(957, 625, 863, 145) = 1
HCF of 957, 625, 863, 145 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 957, 625, 863, 145 is 1.
Highest Common Factor of 957,625,863,145 is 1
Step 1: Since 957 > 625, we apply the division lemma to 957 and 625, to get
957 = 625 x 1 + 332
Step 2: Since the reminder 625 ≠ 0, we apply division lemma to 332 and 625, to get
625 = 332 x 1 + 293
Step 3: We consider the new divisor 332 and the new remainder 293, and apply the division lemma to get
332 = 293 x 1 + 39
We consider the new divisor 293 and the new remainder 39,and apply the division lemma to get
293 = 39 x 7 + 20
We consider the new divisor 39 and the new remainder 20,and apply the division lemma to get
39 = 20 x 1 + 19
We consider the new divisor 20 and the new remainder 19,and apply the division lemma to get
20 = 19 x 1 + 1
We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 957 and 625 is 1
Notice that 1 = HCF(19,1) = HCF(20,19) = HCF(39,20) = HCF(293,39) = HCF(332,293) = HCF(625,332) = HCF(957,625) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 863 > 1, we apply the division lemma to 863 and 1, to get
863 = 1 x 863 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 863 is 1
Notice that 1 = HCF(863,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 145 > 1, we apply the division lemma to 145 and 1, to get
145 = 1 x 145 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 145 is 1
Notice that 1 = HCF(145,1) .
