Given numbers are 649, 156, 616, 104
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 156) = 101244
GCD(649, 156) = ( 649 x 156 ) / 101244
= 649 / 156
= 649
Step2:
LCM(1, 616) = 616
GCD(1, 616) = ( 1 x 616 ) / 616
= 1 / 616
= 1
Step3:
LCM(1, 104) = 104
GCD(1, 104) = ( 1 x 104 ) / 104
= 1 / 104
= 1
So, Greatest Common Divisor of 649, 156, 616, 104 is 1
