GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(421, 781) = 328801
GCD(421, 781) = ( 421 x 781 ) / 328801
= 421 / 781
= 421
Step2:
LCM(1, 707) = 707
GCD(1, 707) = ( 1 x 707 ) / 707
= 1 / 707
= 1
Step3:
LCM(1, 193) = 193
GCD(1, 193) = ( 1 x 193 ) / 193
= 1 / 193
= 1
So, Greatest Common Divisor of 421, 781, 707, 193 is 1
