HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 738, 529, 505, 981 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 738, 529, 505, 981 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 738, 529, 505, 981 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 738, 529, 505, 981 is 1.
HCF(738, 529, 505, 981) = 1
HCF of 738, 529, 505, 981 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 738, 529, 505, 981 is 1.
Highest Common Factor of 738,529,505,981 is 1
Step 1: Since 738 > 529, we apply the division lemma to 738 and 529, to get
738 = 529 x 1 + 209
Step 2: Since the reminder 529 ≠ 0, we apply division lemma to 209 and 529, to get
529 = 209 x 2 + 111
Step 3: We consider the new divisor 209 and the new remainder 111, and apply the division lemma to get
209 = 111 x 1 + 98
We consider the new divisor 111 and the new remainder 98,and apply the division lemma to get
111 = 98 x 1 + 13
We consider the new divisor 98 and the new remainder 13,and apply the division lemma to get
98 = 13 x 7 + 7
We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get
13 = 7 x 1 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 738 and 529 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(98,13) = HCF(111,98) = HCF(209,111) = HCF(529,209) = HCF(738,529) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 505 > 1, we apply the division lemma to 505 and 1, to get
505 = 1 x 505 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 505 is 1
Notice that 1 = HCF(505,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 981 > 1, we apply the division lemma to 981 and 1, to get
981 = 1 x 981 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 981 is 1
Notice that 1 = HCF(981,1) .
