Given numbers are 557, 239, 411, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(557, 239) = 133123
GCD(557, 239) = ( 557 x 239 ) / 133123
= 557 / 239
= 557
Step2:
LCM(1, 411) = 411
GCD(1, 411) = ( 1 x 411 ) / 411
= 1 / 411
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 557, 239, 411, 689 is 1
