HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 755, 87, 774 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 755, 87, 774 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 755, 87, 774 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 755, 87, 774 is 1.
HCF(755, 87, 774) = 1
HCF of 755, 87, 774 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 755, 87, 774 is 1.
Highest Common Factor of 755,87,774 is 1
Step 1: Since 755 > 87, we apply the division lemma to 755 and 87, to get
755 = 87 x 8 + 59
Step 2: Since the reminder 87 ≠ 0, we apply division lemma to 59 and 87, to get
87 = 59 x 1 + 28
Step 3: We consider the new divisor 59 and the new remainder 28, and apply the division lemma to get
59 = 28 x 2 + 3
We consider the new divisor 28 and the new remainder 3,and apply the division lemma to get
28 = 3 x 9 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 755 and 87 is 1
Notice that 1 = HCF(3,1) = HCF(28,3) = HCF(59,28) = HCF(87,59) = HCF(755,87) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 774 > 1, we apply the division lemma to 774 and 1, to get
774 = 1 x 774 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 774 is 1
Notice that 1 = HCF(774,1) .
