HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 739, 1938 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 739, 1938 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 739, 1938 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 739, 1938 is 1.
HCF(739, 1938) = 1
HCF of 739, 1938 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 739, 1938 is 1.
Highest Common Factor of 739,1938 is 1
Step 1: Since 1938 > 739, we apply the division lemma to 1938 and 739, to get
1938 = 739 x 2 + 460
Step 2: Since the reminder 739 ≠ 0, we apply division lemma to 460 and 739, to get
739 = 460 x 1 + 279
Step 3: We consider the new divisor 460 and the new remainder 279, and apply the division lemma to get
460 = 279 x 1 + 181
We consider the new divisor 279 and the new remainder 181,and apply the division lemma to get
279 = 181 x 1 + 98
We consider the new divisor 181 and the new remainder 98,and apply the division lemma to get
181 = 98 x 1 + 83
We consider the new divisor 98 and the new remainder 83,and apply the division lemma to get
98 = 83 x 1 + 15
We consider the new divisor 83 and the new remainder 15,and apply the division lemma to get
83 = 15 x 5 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 739 and 1938 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(83,15) = HCF(98,83) = HCF(181,98) = HCF(279,181) = HCF(460,279) = HCF(739,460) = HCF(1938,739) .
