Given numbers are 358, 858, 557, 388
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(358, 858) = 153582
GCD(358, 858) = ( 358 x 858 ) / 153582
= 358 / 858
= 358
Step2:
LCM(2, 557) = 1114
GCD(2, 557) = ( 2 x 557 ) / 1114
= 2 / 557
= 2
Step3:
LCM(1, 388) = 388
GCD(1, 388) = ( 1 x 388 ) / 388
= 1 / 388
= 1
So, Greatest Common Divisor of 358, 858, 557, 388 is 1
