HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 522, 138, 761 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 522, 138, 761 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 522, 138, 761 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 522, 138, 761 is 1.
HCF(522, 138, 761) = 1
HCF of 522, 138, 761 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 522, 138, 761 is 1.
Highest Common Factor of 522,138,761 is 1
Step 1: Since 522 > 138, we apply the division lemma to 522 and 138, to get
522 = 138 x 3 + 108
Step 2: Since the reminder 138 ≠ 0, we apply division lemma to 108 and 138, to get
138 = 108 x 1 + 30
Step 3: We consider the new divisor 108 and the new remainder 30, and apply the division lemma to get
108 = 30 x 3 + 18
We consider the new divisor 30 and the new remainder 18,and apply the division lemma to get
30 = 18 x 1 + 12
We consider the new divisor 18 and the new remainder 12,and apply the division lemma to get
18 = 12 x 1 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 522 and 138 is 6
Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(30,18) = HCF(108,30) = HCF(138,108) = HCF(522,138) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 761 > 6, we apply the division lemma to 761 and 6, to get
761 = 6 x 126 + 5
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 5 and 6, to get
6 = 5 x 1 + 1
Step 3: We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 761 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(761,6) .
