Given numbers are 262, 280, 525, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(262, 280) = 36680
GCD(262, 280) = ( 262 x 280 ) / 36680
= 262 / 280
= 262
Step2:
LCM(2, 525) = 1050
GCD(2, 525) = ( 2 x 525 ) / 1050
= 2 / 525
= 2
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 262, 280, 525, 645 is 1
