GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(671, 649) = 39589
GCD(671, 649) = ( 671 x 649 ) / 39589
= 671 / 649
= 671
Step2:
LCM(11, 907) = 9977
GCD(11, 907) = ( 11 x 907 ) / 9977
= 11 / 907
= 11
Step3:
LCM(1, 441) = 441
GCD(1, 441) = ( 1 x 441 ) / 441
= 1 / 441
= 1
So, Greatest Common Divisor of 671, 649, 907, 441 is 1
