Given numbers are 690, 160, 497, 221
The list of prime factors of all numbers are
Prime factors of 690 are 2 x 3 x 5 x 23
Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5
Prime factors of 497 are 7 x 71
Prime factors of 221 are 13 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 690, 160, 497, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 160) = 11040
GCD(690, 160) = ( 690 x 160 ) / 11040
= 690 / 160
= 690
Step2:
LCM(10, 497) = 4970
GCD(10, 497) = ( 10 x 497 ) / 4970
= 10 / 497
= 10
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 690, 160, 497, 221 is 1
