GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(198, 705) = 46530
GCD(198, 705) = ( 198 x 705 ) / 46530
= 198 / 705
= 198
Step2:
LCM(3, 548) = 1644
GCD(3, 548) = ( 3 x 548 ) / 1644
= 3 / 548
= 3
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 198, 705, 548, 642 is 1
