HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 859, 658, 940, 245 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 859, 658, 940, 245 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 859, 658, 940, 245 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 859, 658, 940, 245 is 1.
HCF(859, 658, 940, 245) = 1
HCF of 859, 658, 940, 245 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 859, 658, 940, 245 is 1.
Highest Common Factor of 859,658,940,245 is 1
Step 1: Since 859 > 658, we apply the division lemma to 859 and 658, to get
859 = 658 x 1 + 201
Step 2: Since the reminder 658 ≠ 0, we apply division lemma to 201 and 658, to get
658 = 201 x 3 + 55
Step 3: We consider the new divisor 201 and the new remainder 55, and apply the division lemma to get
201 = 55 x 3 + 36
We consider the new divisor 55 and the new remainder 36,and apply the division lemma to get
55 = 36 x 1 + 19
We consider the new divisor 36 and the new remainder 19,and apply the division lemma to get
36 = 19 x 1 + 17
We consider the new divisor 19 and the new remainder 17,and apply the division lemma to get
19 = 17 x 1 + 2
We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get
17 = 2 x 8 + 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 859 and 658 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(19,17) = HCF(36,19) = HCF(55,36) = HCF(201,55) = HCF(658,201) = HCF(859,658) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 940 > 1, we apply the division lemma to 940 and 1, to get
940 = 1 x 940 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 940 is 1
Notice that 1 = HCF(940,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 245 > 1, we apply the division lemma to 245 and 1, to get
245 = 1 x 245 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 245 is 1
Notice that 1 = HCF(245,1) .
