HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 655, 789, 748, 785 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 655, 789, 748, 785 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 655, 789, 748, 785 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 655, 789, 748, 785 is 1.
HCF(655, 789, 748, 785) = 1
HCF of 655, 789, 748, 785 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 655, 789, 748, 785 is 1.
Highest Common Factor of 655,789,748,785 is 1
Step 1: Since 789 > 655, we apply the division lemma to 789 and 655, to get
789 = 655 x 1 + 134
Step 2: Since the reminder 655 ≠ 0, we apply division lemma to 134 and 655, to get
655 = 134 x 4 + 119
Step 3: We consider the new divisor 134 and the new remainder 119, and apply the division lemma to get
134 = 119 x 1 + 15
We consider the new divisor 119 and the new remainder 15,and apply the division lemma to get
119 = 15 x 7 + 14
We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get
15 = 14 x 1 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 655 and 789 is 1
Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(119,15) = HCF(134,119) = HCF(655,134) = HCF(789,655) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 748 > 1, we apply the division lemma to 748 and 1, to get
748 = 1 x 748 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 748 is 1
Notice that 1 = HCF(748,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 785 > 1, we apply the division lemma to 785 and 1, to get
785 = 1 x 785 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 785 is 1
Notice that 1 = HCF(785,1) .
