GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 698) = 461378
GCD(661, 698) = ( 661 x 698 ) / 461378
= 661 / 698
= 661
Step2:
LCM(1, 436) = 436
GCD(1, 436) = ( 1 x 436 ) / 436
= 1 / 436
= 1
Step3:
LCM(1, 968) = 968
GCD(1, 968) = ( 1 x 968 ) / 968
= 1 / 968
= 1
So, Greatest Common Divisor of 661, 698, 436, 968 is 1
