GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(145, 422) = 61190
GCD(145, 422) = ( 145 x 422 ) / 61190
= 145 / 422
= 145
Step2:
LCM(1, 572) = 572
GCD(1, 572) = ( 1 x 572 ) / 572
= 1 / 572
= 1
Step3:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
So, Greatest Common Divisor of 145, 422, 572, 770 is 1
