HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 789, 377 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 487, 789, 377 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 487, 789, 377 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 487, 789, 377 is 1.
HCF(487, 789, 377) = 1
HCF of 487, 789, 377 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 487, 789, 377 is 1.
Highest Common Factor of 487,789,377 is 1
Step 1: Since 789 > 487, we apply the division lemma to 789 and 487, to get
789 = 487 x 1 + 302
Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 302 and 487, to get
487 = 302 x 1 + 185
Step 3: We consider the new divisor 302 and the new remainder 185, and apply the division lemma to get
302 = 185 x 1 + 117
We consider the new divisor 185 and the new remainder 117,and apply the division lemma to get
185 = 117 x 1 + 68
We consider the new divisor 117 and the new remainder 68,and apply the division lemma to get
117 = 68 x 1 + 49
We consider the new divisor 68 and the new remainder 49,and apply the division lemma to get
68 = 49 x 1 + 19
We consider the new divisor 49 and the new remainder 19,and apply the division lemma to get
49 = 19 x 2 + 11
We consider the new divisor 19 and the new remainder 11,and apply the division lemma to get
19 = 11 x 1 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 487 and 789 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(19,11) = HCF(49,19) = HCF(68,49) = HCF(117,68) = HCF(185,117) = HCF(302,185) = HCF(487,302) = HCF(789,487) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 377 > 1, we apply the division lemma to 377 and 1, to get
377 = 1 x 377 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 377 is 1
Notice that 1 = HCF(377,1) .
