HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 222, 647 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 222, 647 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 222, 647 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 222, 647 is 1.
HCF(222, 647) = 1
HCF of 222, 647 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 222, 647 is 1.
Highest Common Factor of 222,647 is 1
Step 1: Since 647 > 222, we apply the division lemma to 647 and 222, to get
647 = 222 x 2 + 203
Step 2: Since the reminder 222 ≠ 0, we apply division lemma to 203 and 222, to get
222 = 203 x 1 + 19
Step 3: We consider the new divisor 203 and the new remainder 19, and apply the division lemma to get
203 = 19 x 10 + 13
We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get
19 = 13 x 1 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 222 and 647 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(203,19) = HCF(222,203) = HCF(647,222) .
