Given numbers are 436, 780, 371, 530
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(436, 780) = 85020
GCD(436, 780) = ( 436 x 780 ) / 85020
= 436 / 780
= 436
Step2:
LCM(4, 371) = 1484
GCD(4, 371) = ( 4 x 371 ) / 1484
= 4 / 371
= 4
Step3:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
So, Greatest Common Divisor of 436, 780, 371, 530 is 1
