Given numbers are 690, 147, 980, 525
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 147) = 33810
GCD(690, 147) = ( 690 x 147 ) / 33810
= 690 / 147
= 690
Step2:
LCM(3, 980) = 2940
GCD(3, 980) = ( 3 x 980 ) / 2940
= 3 / 980
= 3
Step3:
LCM(1, 525) = 525
GCD(1, 525) = ( 1 x 525 ) / 525
= 1 / 525
= 1
So, Greatest Common Divisor of 690, 147, 980, 525 is 1
