Given numbers are 861, 649, 632, 149
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 649) = 558789
GCD(861, 649) = ( 861 x 649 ) / 558789
= 861 / 649
= 861
Step2:
LCM(1, 632) = 632
GCD(1, 632) = ( 1 x 632 ) / 632
= 1 / 632
= 1
Step3:
LCM(1, 149) = 149
GCD(1, 149) = ( 1 x 149 ) / 149
= 1 / 149
= 1
So, Greatest Common Divisor of 861, 649, 632, 149 is 1
