HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 355, 572, 766 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 355, 572, 766 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 355, 572, 766 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 355, 572, 766 is 1.
HCF(355, 572, 766) = 1
HCF of 355, 572, 766 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 355, 572, 766 is 1.
Highest Common Factor of 355,572,766 is 1
Step 1: Since 572 > 355, we apply the division lemma to 572 and 355, to get
572 = 355 x 1 + 217
Step 2: Since the reminder 355 ≠ 0, we apply division lemma to 217 and 355, to get
355 = 217 x 1 + 138
Step 3: We consider the new divisor 217 and the new remainder 138, and apply the division lemma to get
217 = 138 x 1 + 79
We consider the new divisor 138 and the new remainder 79,and apply the division lemma to get
138 = 79 x 1 + 59
We consider the new divisor 79 and the new remainder 59,and apply the division lemma to get
79 = 59 x 1 + 20
We consider the new divisor 59 and the new remainder 20,and apply the division lemma to get
59 = 20 x 2 + 19
We consider the new divisor 20 and the new remainder 19,and apply the division lemma to get
20 = 19 x 1 + 1
We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 355 and 572 is 1
Notice that 1 = HCF(19,1) = HCF(20,19) = HCF(59,20) = HCF(79,59) = HCF(138,79) = HCF(217,138) = HCF(355,217) = HCF(572,355) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 766 > 1, we apply the division lemma to 766 and 1, to get
766 = 1 x 766 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 766 is 1
Notice that 1 = HCF(766,1) .
