Given numbers are 660, 817, 552, 147
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 817) = 539220
GCD(660, 817) = ( 660 x 817 ) / 539220
= 660 / 817
= 660
Step2:
LCM(1, 552) = 552
GCD(1, 552) = ( 1 x 552 ) / 552
= 1 / 552
= 1
Step3:
LCM(1, 147) = 147
GCD(1, 147) = ( 1 x 147 ) / 147
= 1 / 147
= 1
So, Greatest Common Divisor of 660, 817, 552, 147 is 1
