HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 938, 772, 699 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 938, 772, 699 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 938, 772, 699 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 938, 772, 699 is 1.
HCF(938, 772, 699) = 1
HCF of 938, 772, 699 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 938, 772, 699 is 1.
Highest Common Factor of 938,772,699 is 1
Step 1: Since 938 > 772, we apply the division lemma to 938 and 772, to get
938 = 772 x 1 + 166
Step 2: Since the reminder 772 ≠ 0, we apply division lemma to 166 and 772, to get
772 = 166 x 4 + 108
Step 3: We consider the new divisor 166 and the new remainder 108, and apply the division lemma to get
166 = 108 x 1 + 58
We consider the new divisor 108 and the new remainder 58,and apply the division lemma to get
108 = 58 x 1 + 50
We consider the new divisor 58 and the new remainder 50,and apply the division lemma to get
58 = 50 x 1 + 8
We consider the new divisor 50 and the new remainder 8,and apply the division lemma to get
50 = 8 x 6 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 938 and 772 is 2
Notice that 2 = HCF(8,2) = HCF(50,8) = HCF(58,50) = HCF(108,58) = HCF(166,108) = HCF(772,166) = HCF(938,772) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 699 > 2, we apply the division lemma to 699 and 2, to get
699 = 2 x 349 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 699 is 1
Notice that 1 = HCF(2,1) = HCF(699,2) .
