Given numbers are 557, 149, 356, 660
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(557, 149) = 82993
GCD(557, 149) = ( 557 x 149 ) / 82993
= 557 / 149
= 557
Step2:
LCM(1, 356) = 356
GCD(1, 356) = ( 1 x 356 ) / 356
= 1 / 356
= 1
Step3:
LCM(1, 660) = 660
GCD(1, 660) = ( 1 x 660 ) / 660
= 1 / 660
= 1
So, Greatest Common Divisor of 557, 149, 356, 660 is 1
