GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 722) = 468578
GCD(649, 722) = ( 649 x 722 ) / 468578
= 649 / 722
= 649
Step2:
LCM(1, 239) = 239
GCD(1, 239) = ( 1 x 239 ) / 239
= 1 / 239
= 1
Step3:
LCM(1, 147) = 147
GCD(1, 147) = ( 1 x 147 ) / 147
= 1 / 147
= 1
So, Greatest Common Divisor of 649, 722, 239, 147 is 1
