GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 225) = 48150
GCD(642, 225) = ( 642 x 225 ) / 48150
= 642 / 225
= 642
Step2:
LCM(3, 865) = 2595
GCD(3, 865) = ( 3 x 865 ) / 2595
= 3 / 865
= 3
Step3:
LCM(1, 182) = 182
GCD(1, 182) = ( 1 x 182 ) / 182
= 1 / 182
= 1
So, Greatest Common Divisor of 642, 225, 865, 182 is 1
