HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 904, 523, 679 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 904, 523, 679 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 904, 523, 679 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 904, 523, 679 is 1.
HCF(904, 523, 679) = 1
HCF of 904, 523, 679 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 904, 523, 679 is 1.
Highest Common Factor of 904,523,679 is 1
Step 1: Since 904 > 523, we apply the division lemma to 904 and 523, to get
904 = 523 x 1 + 381
Step 2: Since the reminder 523 ≠ 0, we apply division lemma to 381 and 523, to get
523 = 381 x 1 + 142
Step 3: We consider the new divisor 381 and the new remainder 142, and apply the division lemma to get
381 = 142 x 2 + 97
We consider the new divisor 142 and the new remainder 97,and apply the division lemma to get
142 = 97 x 1 + 45
We consider the new divisor 97 and the new remainder 45,and apply the division lemma to get
97 = 45 x 2 + 7
We consider the new divisor 45 and the new remainder 7,and apply the division lemma to get
45 = 7 x 6 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 904 and 523 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(45,7) = HCF(97,45) = HCF(142,97) = HCF(381,142) = HCF(523,381) = HCF(904,523) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 679 > 1, we apply the division lemma to 679 and 1, to get
679 = 1 x 679 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 679 is 1
Notice that 1 = HCF(679,1) .
