HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 716, 777, 818, 145 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 716, 777, 818, 145 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 716, 777, 818, 145 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 716, 777, 818, 145 is 1.
HCF(716, 777, 818, 145) = 1
HCF of 716, 777, 818, 145 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 716, 777, 818, 145 is 1.
Highest Common Factor of 716,777,818,145 is 1
Step 1: Since 777 > 716, we apply the division lemma to 777 and 716, to get
777 = 716 x 1 + 61
Step 2: Since the reminder 716 ≠ 0, we apply division lemma to 61 and 716, to get
716 = 61 x 11 + 45
Step 3: We consider the new divisor 61 and the new remainder 45, and apply the division lemma to get
61 = 45 x 1 + 16
We consider the new divisor 45 and the new remainder 16,and apply the division lemma to get
45 = 16 x 2 + 13
We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get
16 = 13 x 1 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 716 and 777 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(45,16) = HCF(61,45) = HCF(716,61) = HCF(777,716) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 818 > 1, we apply the division lemma to 818 and 1, to get
818 = 1 x 818 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 818 is 1
Notice that 1 = HCF(818,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 145 > 1, we apply the division lemma to 145 and 1, to get
145 = 1 x 145 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 145 is 1
Notice that 1 = HCF(145,1) .
