HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 557, 908, 363, 865 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 557, 908, 363, 865 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 557, 908, 363, 865 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 557, 908, 363, 865 is 1.
HCF(557, 908, 363, 865) = 1
HCF of 557, 908, 363, 865 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 557, 908, 363, 865 is 1.
Highest Common Factor of 557,908,363,865 is 1
Step 1: Since 908 > 557, we apply the division lemma to 908 and 557, to get
908 = 557 x 1 + 351
Step 2: Since the reminder 557 ≠ 0, we apply division lemma to 351 and 557, to get
557 = 351 x 1 + 206
Step 3: We consider the new divisor 351 and the new remainder 206, and apply the division lemma to get
351 = 206 x 1 + 145
We consider the new divisor 206 and the new remainder 145,and apply the division lemma to get
206 = 145 x 1 + 61
We consider the new divisor 145 and the new remainder 61,and apply the division lemma to get
145 = 61 x 2 + 23
We consider the new divisor 61 and the new remainder 23,and apply the division lemma to get
61 = 23 x 2 + 15
We consider the new divisor 23 and the new remainder 15,and apply the division lemma to get
23 = 15 x 1 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 557 and 908 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(23,15) = HCF(61,23) = HCF(145,61) = HCF(206,145) = HCF(351,206) = HCF(557,351) = HCF(908,557) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 363 > 1, we apply the division lemma to 363 and 1, to get
363 = 1 x 363 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 363 is 1
Notice that 1 = HCF(363,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 865 > 1, we apply the division lemma to 865 and 1, to get
865 = 1 x 865 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 865 is 1
Notice that 1 = HCF(865,1) .
