GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(242, 342) = 41382
GCD(242, 342) = ( 242 x 342 ) / 41382
= 242 / 342
= 242
Step2:
LCM(2, 685) = 1370
GCD(2, 685) = ( 2 x 685 ) / 1370
= 2 / 685
= 2
Step3:
LCM(1, 664) = 664
GCD(1, 664) = ( 1 x 664 ) / 664
= 1 / 664
= 1
So, Greatest Common Divisor of 242, 342, 685, 664 is 1
