HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 693, 508, 947 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 693, 508, 947 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 693, 508, 947 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 693, 508, 947 is 1.
HCF(693, 508, 947) = 1
HCF of 693, 508, 947 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 693, 508, 947 is 1.
Highest Common Factor of 693,508,947 is 1
Step 1: Since 693 > 508, we apply the division lemma to 693 and 508, to get
693 = 508 x 1 + 185
Step 2: Since the reminder 508 ≠ 0, we apply division lemma to 185 and 508, to get
508 = 185 x 2 + 138
Step 3: We consider the new divisor 185 and the new remainder 138, and apply the division lemma to get
185 = 138 x 1 + 47
We consider the new divisor 138 and the new remainder 47,and apply the division lemma to get
138 = 47 x 2 + 44
We consider the new divisor 47 and the new remainder 44,and apply the division lemma to get
47 = 44 x 1 + 3
We consider the new divisor 44 and the new remainder 3,and apply the division lemma to get
44 = 3 x 14 + 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 693 and 508 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(44,3) = HCF(47,44) = HCF(138,47) = HCF(185,138) = HCF(508,185) = HCF(693,508) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 947 > 1, we apply the division lemma to 947 and 1, to get
947 = 1 x 947 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 947 is 1
Notice that 1 = HCF(947,1) .
