HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 739, 425, 921 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 739, 425, 921 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, 425, 921 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, 425, 921 is 1.
HCF(739, 425, 921) = 1
HCF of 739, 425, 921 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, 425, 921 is 1.
Highest Common Factor of 739,425,921 is 1
Step 1: Since 739 > 425, we apply the division lemma to 739 and 425, to get
739 = 425 x 1 + 314
Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 314 and 425, to get
425 = 314 x 1 + 111
Step 3: We consider the new divisor 314 and the new remainder 111, and apply the division lemma to get
314 = 111 x 2 + 92
We consider the new divisor 111 and the new remainder 92,and apply the division lemma to get
111 = 92 x 1 + 19
We consider the new divisor 92 and the new remainder 19,and apply the division lemma to get
92 = 19 x 4 + 16
We consider the new divisor 19 and the new remainder 16,and apply the division lemma to get
19 = 16 x 1 + 3
We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get
16 = 3 x 5 + 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 739 and 425 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(92,19) = HCF(111,92) = HCF(314,111) = HCF(425,314) = HCF(739,425) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 921 > 1, we apply the division lemma to 921 and 1, to get
921 = 1 x 921 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 921 is 1
Notice that 1 = HCF(921,1) .
