HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 77, 44, 757 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 77, 44, 757 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, 44, 757 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, 44, 757 is 1.
HCF(77, 44, 757) = 1
HCF of 77, 44, 757 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, 44, 757 is 1.
Highest Common Factor of 77,44,757 is 1
Step 1: Since 77 > 44, we apply the division lemma to 77 and 44, to get
77 = 44 x 1 + 33
Step 2: Since the reminder 44 ≠ 0, we apply division lemma to 33 and 44, to get
44 = 33 x 1 + 11
Step 3: We consider the new divisor 33 and the new remainder 11, and apply the division lemma to get
33 = 11 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 77 and 44 is 11
Notice that 11 = HCF(33,11) = HCF(44,33) = HCF(77,44) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 757 > 11, we apply the division lemma to 757 and 11, to get
757 = 11 x 68 + 9
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 9 and 11, to get
11 = 9 x 1 + 2
Step 3: We consider the new divisor 9 and the new remainder 2, and apply the division lemma to get
9 = 2 x 4 + 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 757 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(757,11) .
