HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 731, 974, 623 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 731, 974, 623 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 731, 974, 623 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 731, 974, 623 is 1.
HCF(731, 974, 623) = 1
HCF of 731, 974, 623 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 731, 974, 623 is 1.
Highest Common Factor of 731,974,623 is 1
Step 1: Since 974 > 731, we apply the division lemma to 974 and 731, to get
974 = 731 x 1 + 243
Step 2: Since the reminder 731 ≠ 0, we apply division lemma to 243 and 731, to get
731 = 243 x 3 + 2
Step 3: We consider the new divisor 243 and the new remainder 2, and apply the division lemma to get
243 = 2 x 121 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 731 and 974 is 1
Notice that 1 = HCF(2,1) = HCF(243,2) = HCF(731,243) = HCF(974,731) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 623 > 1, we apply the division lemma to 623 and 1, to get
623 = 1 x 623 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 623 is 1
Notice that 1 = HCF(623,1) .
