Given numbers are 645, 741, 869, 137
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 741) = 159315
GCD(645, 741) = ( 645 x 741 ) / 159315
= 645 / 741
= 645
Step2:
LCM(3, 869) = 2607
GCD(3, 869) = ( 3 x 869 ) / 2607
= 3 / 869
= 3
Step3:
LCM(1, 137) = 137
GCD(1, 137) = ( 1 x 137 ) / 137
= 1 / 137
= 1
So, Greatest Common Divisor of 645, 741, 869, 137 is 1
