HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 765, 616, 355 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 765, 616, 355 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 765, 616, 355 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 765, 616, 355 is 1.
HCF(765, 616, 355) = 1
HCF of 765, 616, 355 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 765, 616, 355 is 1.
Highest Common Factor of 765,616,355 is 1
Step 1: Since 765 > 616, we apply the division lemma to 765 and 616, to get
765 = 616 x 1 + 149
Step 2: Since the reminder 616 ≠ 0, we apply division lemma to 149 and 616, to get
616 = 149 x 4 + 20
Step 3: We consider the new divisor 149 and the new remainder 20, and apply the division lemma to get
149 = 20 x 7 + 9
We consider the new divisor 20 and the new remainder 9,and apply the division lemma to get
20 = 9 x 2 + 2
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 765 and 616 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(20,9) = HCF(149,20) = HCF(616,149) = HCF(765,616) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 355 > 1, we apply the division lemma to 355 and 1, to get
355 = 1 x 355 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 355 is 1
Notice that 1 = HCF(355,1) .
