GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(254, 780) = 99060
GCD(254, 780) = ( 254 x 780 ) / 99060
= 254 / 780
= 254
Step2:
LCM(2, 636) = 636
GCD(2, 636) = ( 2 x 636 ) / 636
= 2 / 636
= 2
Step3:
LCM(2, 698) = 698
GCD(2, 698) = ( 2 x 698 ) / 698
= 2 / 698
= 2
So, Greatest Common Divisor of 254, 780, 636, 698 is 2
