HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 742, 604, 362, 871 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 742, 604, 362, 871 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 742, 604, 362, 871 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 742, 604, 362, 871 is 1.
HCF(742, 604, 362, 871) = 1
HCF of 742, 604, 362, 871 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 742, 604, 362, 871 is 1.
Highest Common Factor of 742,604,362,871 is 1
Step 1: Since 742 > 604, we apply the division lemma to 742 and 604, to get
742 = 604 x 1 + 138
Step 2: Since the reminder 604 ≠ 0, we apply division lemma to 138 and 604, to get
604 = 138 x 4 + 52
Step 3: We consider the new divisor 138 and the new remainder 52, and apply the division lemma to get
138 = 52 x 2 + 34
We consider the new divisor 52 and the new remainder 34,and apply the division lemma to get
52 = 34 x 1 + 18
We consider the new divisor 34 and the new remainder 18,and apply the division lemma to get
34 = 18 x 1 + 16
We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get
18 = 16 x 1 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 742 and 604 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(34,18) = HCF(52,34) = HCF(138,52) = HCF(604,138) = HCF(742,604) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 362 > 2, we apply the division lemma to 362 and 2, to get
362 = 2 x 181 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 362 is 2
Notice that 2 = HCF(362,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 871 > 2, we apply the division lemma to 871 and 2, to get
871 = 2 x 435 + 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 871 is 1
Notice that 1 = HCF(2,1) = HCF(871,2) .
