HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 767, 444, 128 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 767, 444, 128 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 767, 444, 128 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 767, 444, 128 is 1.
HCF(767, 444, 128) = 1
HCF of 767, 444, 128 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 767, 444, 128 is 1.
Highest Common Factor of 767,444,128 is 1
Step 1: Since 767 > 444, we apply the division lemma to 767 and 444, to get
767 = 444 x 1 + 323
Step 2: Since the reminder 444 ≠ 0, we apply division lemma to 323 and 444, to get
444 = 323 x 1 + 121
Step 3: We consider the new divisor 323 and the new remainder 121, and apply the division lemma to get
323 = 121 x 2 + 81
We consider the new divisor 121 and the new remainder 81,and apply the division lemma to get
121 = 81 x 1 + 40
We consider the new divisor 81 and the new remainder 40,and apply the division lemma to get
81 = 40 x 2 + 1
We consider the new divisor 40 and the new remainder 1,and apply the division lemma to get
40 = 1 x 40 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 767 and 444 is 1
Notice that 1 = HCF(40,1) = HCF(81,40) = HCF(121,81) = HCF(323,121) = HCF(444,323) = HCF(767,444) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 128 > 1, we apply the division lemma to 128 and 1, to get
128 = 1 x 128 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 128 is 1
Notice that 1 = HCF(128,1) .
