HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 307, 780, 829, 139 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 307, 780, 829, 139 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 307, 780, 829, 139 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 307, 780, 829, 139 is 1.
HCF(307, 780, 829, 139) = 1
HCF of 307, 780, 829, 139 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 307, 780, 829, 139 is 1.
Highest Common Factor of 307,780,829,139 is 1
Step 1: Since 780 > 307, we apply the division lemma to 780 and 307, to get
780 = 307 x 2 + 166
Step 2: Since the reminder 307 ≠ 0, we apply division lemma to 166 and 307, to get
307 = 166 x 1 + 141
Step 3: We consider the new divisor 166 and the new remainder 141, and apply the division lemma to get
166 = 141 x 1 + 25
We consider the new divisor 141 and the new remainder 25,and apply the division lemma to get
141 = 25 x 5 + 16
We consider the new divisor 25 and the new remainder 16,and apply the division lemma to get
25 = 16 x 1 + 9
We consider the new divisor 16 and the new remainder 9,and apply the division lemma to get
16 = 9 x 1 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 307 and 780 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(16,9) = HCF(25,16) = HCF(141,25) = HCF(166,141) = HCF(307,166) = HCF(780,307) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 829 > 1, we apply the division lemma to 829 and 1, to get
829 = 1 x 829 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 829 is 1
Notice that 1 = HCF(829,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 139 > 1, we apply the division lemma to 139 and 1, to get
139 = 1 x 139 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 139 is 1
Notice that 1 = HCF(139,1) .
