Given numbers are 246, 720, 421, 637
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(246, 720) = 29520
GCD(246, 720) = ( 246 x 720 ) / 29520
= 246 / 720
= 246
Step2:
LCM(6, 421) = 2526
GCD(6, 421) = ( 6 x 421 ) / 2526
= 6 / 421
= 6
Step3:
LCM(1, 637) = 637
GCD(1, 637) = ( 1 x 637 ) / 637
= 1 / 637
= 1
So, Greatest Common Divisor of 246, 720, 421, 637 is 1
