GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 691) = 169295
GCD(245, 691) = ( 245 x 691 ) / 169295
= 245 / 691
= 245
Step2:
LCM(1, 959) = 959
GCD(1, 959) = ( 1 x 959 ) / 959
= 1 / 959
= 1
Step3:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
So, Greatest Common Divisor of 245, 691, 959, 641 is 1
