GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 664) = 259624
GCD(391, 664) = ( 391 x 664 ) / 259624
= 391 / 664
= 391
Step2:
LCM(1, 970) = 970
GCD(1, 970) = ( 1 x 970 ) / 970
= 1 / 970
= 1
Step3:
LCM(1, 522) = 522
GCD(1, 522) = ( 1 x 522 ) / 522
= 1 / 522
= 1
So, Greatest Common Divisor of 391, 664, 970, 522 is 1
