Given numbers are 645, 747, 620, 262
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 747) = 160605
GCD(645, 747) = ( 645 x 747 ) / 160605
= 645 / 747
= 645
Step2:
LCM(3, 620) = 1860
GCD(3, 620) = ( 3 x 620 ) / 1860
= 3 / 620
= 3
Step3:
LCM(1, 262) = 262
GCD(1, 262) = ( 1 x 262 ) / 262
= 1 / 262
= 1
So, Greatest Common Divisor of 645, 747, 620, 262 is 1
