Given numbers are 650, 645, 695, 450
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(650, 645) = 83850
GCD(650, 645) = ( 650 x 645 ) / 83850
= 650 / 645
= 650
Step2:
LCM(5, 695) = 695
GCD(5, 695) = ( 5 x 695 ) / 695
= 5 / 695
= 5
Step3:
LCM(5, 450) = 450
GCD(5, 450) = ( 5 x 450 ) / 450
= 5 / 450
= 5
So, Greatest Common Divisor of 650, 645, 695, 450 is 5
