GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 308) = 98868
GCD(642, 308) = ( 642 x 308 ) / 98868
= 642 / 308
= 642
Step2:
LCM(2, 832) = 832
GCD(2, 832) = ( 2 x 832 ) / 832
= 2 / 832
= 2
Step3:
LCM(2, 222) = 222
GCD(2, 222) = ( 2 x 222 ) / 222
= 2 / 222
= 2
So, Greatest Common Divisor of 642, 308, 832, 222 is 2
