Given numbers are 645, 282, 691, 534
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 282) = 60630
GCD(645, 282) = ( 645 x 282 ) / 60630
= 645 / 282
= 645
Step2:
LCM(3, 691) = 2073
GCD(3, 691) = ( 3 x 691 ) / 2073
= 3 / 691
= 3
Step3:
LCM(1, 534) = 534
GCD(1, 534) = ( 1 x 534 ) / 534
= 1 / 534
= 1
So, Greatest Common Divisor of 645, 282, 691, 534 is 1
