HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 777, 602, 724, 219 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 777, 602, 724, 219 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 777, 602, 724, 219 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 777, 602, 724, 219 is 1.
HCF(777, 602, 724, 219) = 1
HCF of 777, 602, 724, 219 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 777, 602, 724, 219 is 1.
Highest Common Factor of 777,602,724,219 is 1
Step 1: Since 777 > 602, we apply the division lemma to 777 and 602, to get
777 = 602 x 1 + 175
Step 2: Since the reminder 602 ≠ 0, we apply division lemma to 175 and 602, to get
602 = 175 x 3 + 77
Step 3: We consider the new divisor 175 and the new remainder 77, and apply the division lemma to get
175 = 77 x 2 + 21
We consider the new divisor 77 and the new remainder 21,and apply the division lemma to get
77 = 21 x 3 + 14
We consider the new divisor 21 and the new remainder 14,and apply the division lemma to get
21 = 14 x 1 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 777 and 602 is 7
Notice that 7 = HCF(14,7) = HCF(21,14) = HCF(77,21) = HCF(175,77) = HCF(602,175) = HCF(777,602) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 724 > 7, we apply the division lemma to 724 and 7, to get
724 = 7 x 103 + 3
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 3 and 7, to get
7 = 3 x 2 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 724 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(724,7) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 219 > 1, we apply the division lemma to 219 and 1, to get
219 = 1 x 219 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 219 is 1
Notice that 1 = HCF(219,1) .
