HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 866, 357 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 487, 866, 357 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 487, 866, 357 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 487, 866, 357 is 1.
HCF(487, 866, 357) = 1
HCF of 487, 866, 357 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 487, 866, 357 is 1.
Highest Common Factor of 487,866,357 is 1
Step 1: Since 866 > 487, we apply the division lemma to 866 and 487, to get
866 = 487 x 1 + 379
Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 379 and 487, to get
487 = 379 x 1 + 108
Step 3: We consider the new divisor 379 and the new remainder 108, and apply the division lemma to get
379 = 108 x 3 + 55
We consider the new divisor 108 and the new remainder 55,and apply the division lemma to get
108 = 55 x 1 + 53
We consider the new divisor 55 and the new remainder 53,and apply the division lemma to get
55 = 53 x 1 + 2
We consider the new divisor 53 and the new remainder 2,and apply the division lemma to get
53 = 2 x 26 + 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 487 and 866 is 1
Notice that 1 = HCF(2,1) = HCF(53,2) = HCF(55,53) = HCF(108,55) = HCF(379,108) = HCF(487,379) = HCF(866,487) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 357 > 1, we apply the division lemma to 357 and 1, to get
357 = 1 x 357 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 357 is 1
Notice that 1 = HCF(357,1) .
