HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 788, 552, 770 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 788, 552, 770 is 2 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 788, 552, 770 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 788, 552, 770 is 2.
HCF(788, 552, 770) = 2
HCF of 788, 552, 770 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 788, 552, 770 is 2.
Highest Common Factor of 788,552,770 is 2
Step 1: Since 788 > 552, we apply the division lemma to 788 and 552, to get
788 = 552 x 1 + 236
Step 2: Since the reminder 552 ≠ 0, we apply division lemma to 236 and 552, to get
552 = 236 x 2 + 80
Step 3: We consider the new divisor 236 and the new remainder 80, and apply the division lemma to get
236 = 80 x 2 + 76
We consider the new divisor 80 and the new remainder 76,and apply the division lemma to get
80 = 76 x 1 + 4
We consider the new divisor 76 and the new remainder 4,and apply the division lemma to get
76 = 4 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 788 and 552 is 4
Notice that 4 = HCF(76,4) = HCF(80,76) = HCF(236,80) = HCF(552,236) = HCF(788,552) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 770 > 4, we apply the division lemma to 770 and 4, to get
770 = 4 x 192 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 770 is 2
Notice that 2 = HCF(4,2) = HCF(770,4) .
