HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 737, 858, 487 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 737, 858, 487 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 737, 858, 487 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 737, 858, 487 is 1.
HCF(737, 858, 487) = 1
HCF of 737, 858, 487 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 737, 858, 487 is 1.
Highest Common Factor of 737,858,487 is 1
Step 1: Since 858 > 737, we apply the division lemma to 858 and 737, to get
858 = 737 x 1 + 121
Step 2: Since the reminder 737 ≠ 0, we apply division lemma to 121 and 737, to get
737 = 121 x 6 + 11
Step 3: We consider the new divisor 121 and the new remainder 11, and apply the division lemma to get
121 = 11 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 737 and 858 is 11
Notice that 11 = HCF(121,11) = HCF(737,121) = HCF(858,737) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 487 > 11, we apply the division lemma to 487 and 11, to get
487 = 11 x 44 + 3
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 3 and 11, to get
11 = 3 x 3 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 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 11 and 487 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(487,11) .
