The list of prime factors of all numbers are
Prime factors of 690 are 2 x 3 x 5 x 23
Prime factors of 513 are 3 x 3 x 3 x 19
Prime factors of 370 are 2 x 5 x 37
Prime factors of 291 are 3 x 97
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 690, 513, 370, 291
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 513) = 117990
GCD(690, 513) = ( 690 x 513 ) / 117990
= 690 / 513
= 690
Step2:
LCM(3, 370) = 1110
GCD(3, 370) = ( 3 x 370 ) / 1110
= 3 / 370
= 3
Step3:
LCM(1, 291) = 291
GCD(1, 291) = ( 1 x 291 ) / 291
= 1 / 291
= 1
So, Greatest Common Divisor of 690, 513, 370, 291 is 1
