GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 535) = 353635
GCD(661, 535) = ( 661 x 535 ) / 353635
= 661 / 535
= 661
Step2:
LCM(1, 529) = 529
GCD(1, 529) = ( 1 x 529 ) / 529
= 1 / 529
= 1
Step3:
LCM(1, 980) = 980
GCD(1, 980) = ( 1 x 980 ) / 980
= 1 / 980
= 1
So, Greatest Common Divisor of 661, 535, 529, 980 is 1
