Given numbers are 140, 686, 557, 535
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 686) = 6860
GCD(140, 686) = ( 140 x 686 ) / 6860
= 140 / 686
= 140
Step2:
LCM(14, 557) = 7798
GCD(14, 557) = ( 14 x 557 ) / 7798
= 14 / 557
= 14
Step3:
LCM(1, 535) = 535
GCD(1, 535) = ( 1 x 535 ) / 535
= 1 / 535
= 1
So, Greatest Common Divisor of 140, 686, 557, 535 is 1
