Given numbers are 690, 897, 557, 109
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 897) = 8970
GCD(690, 897) = ( 690 x 897 ) / 8970
= 690 / 897
= 690
Step2:
LCM(69, 557) = 38433
GCD(69, 557) = ( 69 x 557 ) / 38433
= 69 / 557
= 69
Step3:
LCM(1, 109) = 109
GCD(1, 109) = ( 1 x 109 ) / 109
= 1 / 109
= 1
So, Greatest Common Divisor of 690, 897, 557, 109 is 1
