HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 77, 654, 591, 855 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 77, 654, 591, 855 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 77, 654, 591, 855 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 77, 654, 591, 855 is 1.
HCF(77, 654, 591, 855) = 1
HCF of 77, 654, 591, 855 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 77, 654, 591, 855 is 1.
Highest Common Factor of 77,654,591,855 is 1
Step 1: Since 654 > 77, we apply the division lemma to 654 and 77, to get
654 = 77 x 8 + 38
Step 2: Since the reminder 77 ≠ 0, we apply division lemma to 38 and 77, to get
77 = 38 x 2 + 1
Step 3: We consider the new divisor 38 and the new remainder 1, and apply the division lemma to get
38 = 1 x 38 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 77 and 654 is 1
Notice that 1 = HCF(38,1) = HCF(77,38) = HCF(654,77) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 591 > 1, we apply the division lemma to 591 and 1, to get
591 = 1 x 591 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 591 is 1
Notice that 1 = HCF(591,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 855 > 1, we apply the division lemma to 855 and 1, to get
855 = 1 x 855 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 855 is 1
Notice that 1 = HCF(855,1) .
