HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 123, 601, 788 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 123, 601, 788 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 123, 601, 788 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 123, 601, 788 is 1.
HCF(123, 601, 788) = 1
HCF of 123, 601, 788 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 123, 601, 788 is 1.
Highest Common Factor of 123,601,788 is 1
Step 1: Since 601 > 123, we apply the division lemma to 601 and 123, to get
601 = 123 x 4 + 109
Step 2: Since the reminder 123 ≠ 0, we apply division lemma to 109 and 123, to get
123 = 109 x 1 + 14
Step 3: We consider the new divisor 109 and the new remainder 14, and apply the division lemma to get
109 = 14 x 7 + 11
We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get
14 = 11 x 1 + 3
We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get
11 = 3 x 3 + 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 123 and 601 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(109,14) = HCF(123,109) = HCF(601,123) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 788 > 1, we apply the division lemma to 788 and 1, to get
788 = 1 x 788 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 788 is 1
Notice that 1 = HCF(788,1) .
