Given numbers are 987, 660, 153, 604
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 660) = 217140
GCD(987, 660) = ( 987 x 660 ) / 217140
= 987 / 660
= 987
Step2:
LCM(3, 153) = 153
GCD(3, 153) = ( 3 x 153 ) / 153
= 3 / 153
= 3
Step3:
LCM(3, 604) = 1812
GCD(3, 604) = ( 3 x 604 ) / 1812
= 3 / 604
= 3
So, Greatest Common Divisor of 987, 660, 153, 604 is 1
