Given numbers are 535, 777, 407, 640
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(535, 777) = 415695
GCD(535, 777) = ( 535 x 777 ) / 415695
= 535 / 777
= 535
Step2:
LCM(1, 407) = 407
GCD(1, 407) = ( 1 x 407 ) / 407
= 1 / 407
= 1
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 535, 777, 407, 640 is 1
